Replacing traditional Fuses with Trip switches

Discussion in ' Electricians' Talk ' started by DJU , Oct 6, 2004 .

I am buying a property which has the good old fuse box with fuses that you have to replace the wire on. I noticed that he had 1 fuse that was a trip switch (looks like an mcb). Does anyone know where I can find these as I would like to change them all and I don't want to buy a new consumer unit. I have never seen a trip switch that you can put in the old fuse boxes.

How to Fix a Tripped fuse or switch – An Electrician’s Guide

Fixing a tripped fuse or switch : an electrician’s guide.

Dealing with a tripped fuse or switch can be a hassle, but it’s a common issue that every homeowner faces. Whether it’s caused by an overloaded circuit, a power surge, or a faulty appliance, knowing how to address this problem can save you time and stress. In this blog post, we’ll guide you through the process of diagnosing and fixing a tripped fuse or switch. With our step-by-step instructions and safety tips, you’ll be able to restore power to your home quickly and safely. So, let’s get started on turning those lights back on and getting your appliances running smoothly again.

Identify the Problem

To address a tripped fuse, you should first identify and correct the underlying cause. There are two fuseboard types and working on them have unique approaches. In this article are some details on fuse box types and how to address the problem for each. If you’re unsure or uncomfortable dealing with electrical issues, it’s advisable to contact an electrician .

Note: Do not attempt to resolve tripped switches or fuse boxes if you are uncertain about the cause.

Fuse board types

There are two main fuse box types basically we have the old school fuse boxes and the modern fuse boxes also now widely known as consumer units or fuse boards.

Differences between Old fuse boxes and Consumer Units

Old fuse boxes have fuses that blow up should there be an anomaly in your electrical system and require a manual replacement. Now with these modern consumer units, the switches go off immediately there is a fault, with no smell of burnt fuse and noise of fuses blowing up. And that is why it is the modern world. What are the differences between old fuse boxes and new ones?

In both cases you will have to identify the underlying cause as mentioned earlier before attempting to replace fuses or put the switches back on.

What anomalies cause the switches to trip or fuses to blow?

• An overloaded circuit
• Too many appliances being used at the same time.
• A faulty or misused appliances
• Faulty immersion heaters
• Faulty connections to appliances e.g., televisions or stereos etc.
• Light bulbs blowing
• Short circuits
• Ground faults
• Loose Wiring
• Old or Damaged Wiring
• Faulty Circuit Breaker

How to fix tripped switches on Consumer units?

To fix a tripped switch on new consumer units,

First open the fuse board and check to see if any of the switches are off. Use the indicators on the switch or the fuse box to determine that. In most cases, the switch facing upwards means “ON” and it facing downwards means “OFF”. Turn all those off back on and if it does not stay on, you probably have another issue to resolve or the underlying issue was not fixed properly.

How to fix tripped fuse on Old Fuse box?

To fix a tripped fuse on an old fuse box,

• Turn off the power source.
• Take out the blown fuse and insert a replacement.
• Then switch the power back on.

To find the right replacement it is best you send the blown fuse along when getting a new one if you don’t understand much about electrical writings.

Tip: If a fuse or switch trips, unplug some devices on the affected circuit before resetting it. Overloading is a common cause, so reducing the load can help prevent future trips. If the issue continues, it may indicate a more serious problem needing help from experts .

What to do if the switch goes back off after switching it on?

Should you face the challenge of the switch not staying on it means one or some electrical appliances have a fault. You can narrow down on what is causing it by turning off all the switches and turning them on one by one to see which part of your property does not have functioning electrical systems. You can also just go around the house and see what appliance stopped working. Either way you will know exactly what is causing the issue and you may need to call on qualified electricians to come to your rescue.

An electrician’s guide on how to fix a tripped fuse

Any kind of major electrical fault around the house will need to be repaired by a professional electrician. However, that said, there are a few everyday electrical tasks that aren’t complicated, or dangerous, which you could attempt yourself. The most important thing to remember is to switch off and unplug whatever it is you need to work on so there’s no danger of a live current.

The first thing to do is find your main fuse box (these days called a consumer unit), which will be in the same place as your electricity meter. They’re often in the main hallway of a house, in a purpose-built cupboard. This is where the electricity in your house is controlled from, and it’s important that you know where to go and what to do if you need to turn off the mains electricity. It’s also helpful to remember where you left a torch too!

In the case of loss of electric light or power

Your fuse box, or consumer unit, will either have fuses or trip switches. Modern electric circuits are fitted with a circuit breaker fuse system; if a fault develops, a switch is tripped and the circuit is broken. Older ones have fuse holders and when a fuse is blown it must be replaced or rewired.

If you experience problems with an old-fashioned fuse box, it might be sensible to install a replacement which conforms to current regulations for ease, safety and peace of mind. If you need assistance with any kind of electrical installation we would recommend calling out a qualified electrician .

Setting a trip switch Open the cover on the consumer unit to see which switches have tripped to the OFF position. Put them back to the ON position. If tripping occurs again, it is probably being caused by a faulty appliance. You need to identify which circuit is affected and which appliance on that circuit is causing the problem.

Which appliance is faulty?

Go around the house noting which set of lights or sockets are not working. Unplug all appliances on that problem circuit and switch off any immersion heaters (if you have one). Switch the tripped switch to the ON position and plug in the appliances one by one until the trip goes again. Leave that appliance unplugged, and have it repaired by a qualified electrician.

What causes it to trip or blow a fuse?

• An overloaded circuit
• Too many appliances being used at the same time
• A faulty or misused appliance
• Overfilled kettles
• Unclean toasters
• Cooker rings worn out or cracked
• Faulty immersion heaters
• Faulty connections on leads to appliances e.g. televisions or stereos etc.
• Light bulbs blowing

Most plugs will have a fuse inside them. If the appliance suddenly stops working, it is worth replacing the fuse inside the plug before calling an electrician.

To find out the correct type of fuse to fit in the plug, check the rating plate on the appliance. Do not overload plug sockets by using multiple plug adaptors.

Replacing the plug on an appliance is fairly straightforward, and is well worth doing before you declare your electrical appliance broken.

• Do not tamper with the electricity company’s fuse and seals
• Do not take any action unless you are confident you can do it safely and legally

At some point, all London homeowners and landlords will likely encounter the frustrating power cut-off of a tripped fuse. For many, the first instinct might be to call an electrician immediately.

But what if there was a simple fix you could perform safely and swiftly?

This guide will explain to you how to identify and reset a tripped fuse. By the end, you'll be equipped to handle this common electrical issue on your own, saving you time and money while enhancing home safety.

Well, Before we jump into the nitty-gritty, it's important to understand the difference between a fuse and a breaker in the first place.

What Is The Difference Between a Fuse And a Breaker?

13 Amp, 3 Amp and 5 Amp fuses in the UK

NXB-125 Moulded Case Circuit Breaker

The main difference is that fuses can't be used again, but breakers can be used many times. Breakers shield homes and devices from overloading and short-circuiting, while fuses only protect against overloading.

Both fuses and breakers stop the electricity flow, but they work differently. A fuse melts metal when it gets too hot, while a breaker switches off when there's too much electricity.

What Causes a Tripped Circuit Breaker?

The main reason a circuit breaker trips is when there's too much electricity (power surge), overloading the circuit because of too many lights, devices, or appliances using the same circuit.

The main breaker is on the right side, and the other breaker is on the left side.

What Causes a Fuse To Trip or Blow?

Fuses can trip or blow if you're using more electricity than the circuit can handle. This happens when you plug in too many devices or appliances at once, putting a strain on the electrical system.

Running too many appliances at the same time can overwhelm the circuit, causing the fuse to trip. This often occurs when multiple high-power devices operate simultaneously, drawing more electricity than the circuit can safely handle.

A defective or misused appliance can also lead to a blown fuse. If an appliance has a short circuit or a malfunctioning component, it can cause a surge of electricity that exceeds the capacity of the fuse, resulting in a trip.

Overfilling kettles or having dirty toasters can create electrical problems. When water or crumbs touch electrical parts, they lead to a short circuit, resulting in a blown fuse.

Worn-out or cracked cooker rings can cause electrical faults that trip the fuse. Over time, the heating elements in cookers can deteriorate, leading to increased resistance and potential overheating.

Faulty immersion heaters can also trip fuses. If the heating element becomes damaged or the thermostat malfunctions, the circuit can overload, causing the fuse to blow.

Faulty connections on appliance leads, such as those for TVs or stereos, can result in electrical issues. Loose or damaged connections can create resistance in the circuit, leading to overheating and fuse failure.

If light bulbs frequently blow out, it could indicate an underlying electrical problem. This could be due to issues such as voltage fluctuations, poor wiring, or incompatible bulbs, all of which can cause fuses to trip or blow.

What If My Fuse Box Keeps Tripping?

Uh-oh! Lights out? Sockets dead? Fuse box acting up again? We understand your frustration! It's common for breakers to trip or fuses to blow occasionally, but if this happens frequently, there might be a larger problem at hand.

Fuses play a crucial role in electrical circuits, ensuring our safety. When a fuse trips, it's a warning sign that something might be wrong with an appliance or wiring in your home.

If you've followed the steps above and still can't figure out why your fuse keeps tripping or if it happens repeatedly, the problem might lie with the fuse box itself.

The fuse starts to break the circuit when the current is too high, preventing electrical damage and fires.

You can usually pinpoint the problem by elimination. If the problem persists, don't hesitate to contact Serviceteam Professional Electricians in London for a reliable service.

How To Fix an Electrical Issue At Home?

Here are some steps to help you troubleshoot electrical issues at home:

Look for any faulty or damaged items that may be causing problems. If you find any, unplug or replace them.

Look for signs of burning, discolouration, or unusual smells. Check for frayed or exposed wires. If you notice any issues, it's best to call a licensed and experienced electrician to assess and repair them.

Rodents like rats, mice, and chipmunks are known for chewing through electrical wires, which can lead to dangerous situations. If you suspect pests are present in your home, contact an exterminator to address the issue.

Make sure the breaker of the correct size is being used for each circuit. Ensure that all breakers are secure, and there are no sparks or signs of burning.

Here are some signs to look out for:

• The main breaker trips, but the individual breakers seem fine.
• The breaker won't reset properly.
• You notice a burning smell coming from the electrical box.
• The circuit breaker keeps tripping frequently.
• There are signs of damage to a breaker, such as scorch marks.

If you spot any issues, contact a licensed electrician for repairs. Remember not to attempt any electrical work unless you're completely confident in your abilities.

Always prioritise safety when dealing with electrical issues. If you're unsure or don't have the right tools, it's best to hire a professional electrician who can safely handle the situation.

Signs of a Tripped Fuse

How can you tell if you're dealing with a tripped fuse ? Look for a power shut-off in one area of your home, frequently accompanied by a loss of lighting.

In some cases, the fuse box might show a red indicator or the switch corresponding to the affected area will be in an 'off' position.

[The Step-by-Step Guide]

How To Fix a Tripped Fuse?

There is no need to panic when you discover a fuse box switch is tripped; just follow these simple steps.

Before attempting to reset the fuse, the first and most critical step is to switch off all appliances and lights connected to the circuit that you suspect is tripped. This helps prevent further overload and reduces the risk of electrical hazards.

Once everything is powered down, find your electrical panel. In most London homes, this is a grey metal box found in a hallway, basement, or other utility area. Knowing where your panel is located before an emergency is crucial so you can access it easily.

The first step in fixing a tripped fuse is identifying the problem. When a fuse trips, it's typically due to an overload or short circuit in the electrical system. Start by locating your fuse box, usually found in the basement, garage, or utility room. Open the fuse box, and you'll see a series of on-off switches known as circuit breakers. Each switch controls the electricity to a different part of your home and is labelled accordingly. Scan these switches until you find one that's in the 'off' position, or if you have an older fuse box, you may notice a fuse with a visible break or burn mark.

Now you have switched off all appliances. To reset the fuse, simply flip the switch back to the "on" position. If you have a fuse system, replace it with another one with the same amperage rating.

After resetting the fuse, test the circuit by gradually turning on appliances and lights one by one to ensure the system can handle the load. If the fuse trips again immediately, it could indicate a more serious underlying issue, and you may need to seek professional help from a qualified electrician.

If the fuse remains intact after testing the circuit, you've successfully resolved the issue! However, to prevent future incidents, it's essential to address the cause of the tripped fuse. Common causes include overloaded circuits, faulty appliances, or wiring issues. Consider redistributing appliances across different circuits or having defective appliances repaired or replaced.

These simple steps allow London homeowners to quickly and safely restore power.

Expert Tips to Prevent Future Trips and Blown Fuses

• Check your appliances and devices to see if any are faulty or damaged.

👉 If you're looking for reliable electrical services, such as Portable Appliance Testing (PAT) , EICR or any other electrical need, in London, give serviceteam's professional electricians a call. Make sure to get your PAT testing done on time. It checks all the portable devices in a building or at a construction site that are connected to the main electrical supply. This includes appliances like refrigerators, electric cookers, kettles, toasters, TVs, drills, hair dryers, and anything else that you plug into a socket! Ensure your home's electrical safety for peace of mind.

• Make sure you're not overloading any circuits with too many devices plugged in.
• Unplug or replace any appliances or devices that could be causing the problem.

For Long-Term Prevention:

• Regularly inspect your electrical panel for signs of damage.
• Avoid overloading outlets with multiple devices.
• Unplug devices when they're not in use.
• Replace worn or damaged electrical cords.
• Use surge protectors to safeguard your appliances and devices from power surges.
• Avoid doing electrical work yourself if you're not trained or experienced.

How Do I Know If I've Overloaded a Circuit?

Circuits can safely handle a specific amount of electricity. Using too many devices at once can draw more electricity than the circuit can handle. This causes the fuse to trip.

If you've been using multiple appliances in one room, you've probably overloaded the circuit. Extension cords are often the culprit. Even though they have multiple sockets, it's not safe to use all of them simultaneously. Try unplugging some devices and then switch the tripped fuse back to the "on" position.

Safety Measures

When dealing with electricity, safety has to be the top priority. Therefore, make sure you wear appropriate safety gear such as gloves and, if possible, non-conductive footwear.

When to Call a Professional Electrician

If the circuit trips again immediately after being reset or the breaker switch keeps turning off without apparent cause, it's time to bring in a professional. Some problems may be too complex or dangerous for an amateur to handle, so if in doubt, seek expert help from a qualified electrician.

Remember these simple steps, and the next time your home encounters a tripped fuse, approach the situation calmly and confidently.

Our professional electricians are just a call away, ready to step in and ensure your home's electrical systems are in top-notch condition.

Guide to Resetting a Tripped Breaker or Fixing a Blown Fuse

It is common for homeowners to run into a tripped breaker or blown fuse every once in a while. We often get calls to our service line asking how to reset one, and we are always happy to help! However, we want to give you a written step-by-step guide that you can come back to for future reference.

To begin, you will need to make sure all lights are off in the rooms where power was impacted. Now unplug any appliance (like a toaster) that was recently plugged in in these rooms, as it is likely this was the cause. Make sure this is completed first in order to ensure that you do not trip the breaker again after you fix it the first time!

Next, locate your electric panel. Open it and examine the safety of the situation before you begin. You should have dry hands and be standing on a dry surface the entire time. If at any point you feel unsafe or unsure about what you are doing, please give us a call at 314-441-5200. We do not want you to harm yourself during this process.

Blown Fuse:  If you are working with an electrical panel with fuses, begin checking each fuse. You are trying to see if the piece of metal inside the fuse has melted or if the glass at the top of the fuse has become discolored. The glass at the top of a blown fuse will usually be purple or brown. Unscrew the fuse and replace it with a new one that is exactly the same as the old one in size, type, and amperage.

Tripped Breaker:  If you are working with a tripped breaker, simply look for any breaker that has moved from the “on” to the “off” position, or that is somewhere in the middle. You have now identified the tripped breaker. Switch this breaker fully to the “off” position and then switch back over to “on”. Your power will now be restored!

To test, plug a few things back in and turn them on to test your new fuse or reset breaker. If everything comes back on, congratulations – you have successfully fixed the issue! If you lose power again while plugging things back in, try moving some appliances to other outlets in the room. It may be that you are using too many amps and the breaker cannot support them. If you do this and it still does not fix the problem, there may be a more serious issue at hand. Please call us at 314-441-5200 if that is the case!

Electrical Blog - Troubleshooting Tripped Fuses: A Guide to Handling Electrical Issues

Electricity is a fundamental necessity in our homes, and when a fuse trips, it can be both frustrating and disruptive. Knowing how to handle this situation is crucial, as it can save you from unnecessary inconveniences and potential hazards. This article provides insight into what causes fuses to trip and offers a step-by-step guide on how to address the issue.

Common Causes of Tripped or Blown Fuses

Understanding the root causes of tripped or blown fuses is the first step in resolving the issue. Here are some common culprits:

Overloaded Circuits: Too many appliances plugged into a single circuit can overload it and cause the fuse to trip.

Faulty Appliances: An appliance with a malfunction or defect can trip a fuse.

Improper Appliance Usage: Using an appliance inappropriately, such as overfilling a kettle or running it beyond its capacity, can lead to a fuse tripping.

Faulty Immersion Heaters: Malfunctioning immersion heaters can also be a source of trouble.

Blown Lightbulbs: A blown lightbulb can sometimes trigger a fuse to trip.

Worn Cooker Rings: Worn-out or damaged cooker rings can overload the circuit.

What to Do When a Fuse Trips

Locate Your Fuse Box: Your fuse box, usually located near the electricity meter, is the first place to go when a fuse trips.

Identify the Problem: Examine your fuse box to determine whether it contains fuses or trip switches. In modern installations, trip switches are often used. A tripped switch shifts the power circuit from the "on" position to the "off" position.

Reset the Trip Switch: If you have trip switches, it's relatively easy to identify the problem. The tripped switch will be in the "off" position, usually indicated by the color red. Simply push it back up to the "on" position, typically shown in green. If the switch immediately flips back down, it's an indicator that a faulty appliance is connected to the circuit.

Identifying a Faulty Appliance

Unplug All Appliances: Start by unplugging all appliances connected to the circuit. If you have an immersion heater, ensure it's turned off.

Reset the Trip Switch: After everything is unplugged, reset the trip switch to the "on" position. It should remain on this time.

Plug in Appliances One by One: Gradually plug in each item that you've unplugged. Continue this process until the fuse trips again, at which point you've identified the problematic appliance.

Address the Faulty Appliance: Keep the faulty appliance unplugged and take it to a nearby electrical specialist for repair. If the faulty item has a plug, consider changing the fuse in the plug before getting it repaired. This is a straightforward process similar to changing a battery.

By following these steps, you can efficiently troubleshoot and resolve a tripped fuse, ensuring a safe and functional electrical system in your home. Remember, electrical issues should always be approached with caution, and if you're unsure, it's best to seek professional assistance to ensure your safety and that of your property.

What To Do If: Your Fuse Keeps Tripping

Electricity is one of the basic essentials in our homes, coming before almost anything else. If a fuse goes, it can be frustrating, but it helps to know what to do and when to call an electrician.

Causes of tripped or blown fuses

Finding out the cause of a tripped or blown fuse usually involves a process of elimination and a little patience. Most common causes are:

• Too many appliances plugged in
• A faulty appliance
• An appliance that is not maintained or is used inappropriately (e.g. overfilled kettle)
• Faulty immersion heaters
• Blown lightbulb
• Worn cooker rings.

If a fuse goes…

If a fuse goes, head straight to your fuse box, which is near your meter. Hopefully, you will know where it is and how to access it already. Your fuse box will have either fuses or trip switches. If a fuse “blows” then you will have to replace it in order to regain power. Trip switches are a more modern alternative to fuses. Rather than the fuse physically breaking, the switch is tripped and the power circuit goes from “on” to “off”.

Reset the trip switch

If a trip switch has gone, you should easily be able to see which one is the problem as the lever will be in the down position (usually showing “off” in red). Simply push the switch back up, to show “on” in green. If the switch flips down immediately, that is a sign that you have a faulty appliance plugged in somewhere. This is where the fun starts!

Finding a faulty appliance

It is most likely that only one circuit has tripped.

• Make a note of the appliances that aren’t working and unplug each one. If you have an immersion heater, switch it off.
• Once everything is unplugged, flip the trip switch to ON. It should stay on this time.
• Now go around the house and plug in each item that you have unplugged.
• Keep plugging appliances in until the fuse trips again; you have identified your culprit!
• Keep the faulty appliance unplugged (you can switch the trip back on now) and take it to a nearby electrical specialist for repair.

If the faulty item has a plug, it is worth changing the fuse in the plug before you take the appliance to be repaired. Replacing a fuse is not dissimilar to changing a battery. Unscrew the cover and look at the fuse in the plug already, or check the rating on the plug to find out what fuse you need. Once you know what fuse to use, it is a case of removing the old fuse, and popping a new one in.

While it is fine to attempt to do a range of home repairs yourself, when it comes to electrical faults, it is best left to the professionals.

• Skill Level: Beginner
• Estimated Cost: $0

A power breaker trip is an annoying occurrence when the power shuts off and you can't use the microwave, lights, or router. A breaker trip is far more than simply annoying when you need that router to send off a time-sensitive work assignment or when medical devices are diverted to time-limited standby power. Fortunately, it's easy to fix a circuit breaker trip in just a few minutes.

Tripped Circuit Breaker

A tripped circuit breaker is when a circuit breaker automatically shuts off to prevent devices on the circuit from overheating or from receiving excessive power. A circuit breaker protects your home against damaging or harmful short circuits and overloads.

• Overloaded circuits : When too many devices are operating on the same circuit and are attempting to pull a higher power load than the circuit can carry, the circuit breaker will trip.
• High-power devices : High amp devices like microwaves , dryers , wall heaters , or A/Cs are turned on for sustained periods, they can cause a power breaker trip.
• Short circuits : In a short circuit, a powered or hot wire makes contact with a neutral wire or when wires are loosened .
• Ground faults: In a ground fault, a hot wire touches anything that is grounded, such as the side of a metal electrical box , an appliance, an outlet , or a bare ground wire.

Watch Now: How to Safely Reset a Tripped Circuit Breaker

Working around an electrical service panel or circuit breaker board can be dangerous. Your home’s entire electrical load is contained in that box, concentrated around the metal lugs where the service drop’s wires enter the box. Unscrewing and removing the inner dead-front cover within the service panel exposes the highly powered lugs.

What You'll Need

Equipment / tools.

• Circuit breaker directory (if available)
• Rubber-soled shoes
• Safety glasses

Instructions

Locate a flashlight.

Circuit breaker panels tend to be located in out-of-the-way locations with little, if any, ambient light. Find a flashlight. Use the light from a phone if necessary.

Turn Off Devices on the Circuit

Turn off all devices on the electrical circuit. This includes the device that may have caused the breaker to trip, such as a microwave, hairdryer, or A/C, plus all other devices on the same circuit.

Find the Electric Service Panel

The electric service panel, sometimes called a circuit breaker board, is a metal box with a door. The box may be inset in a wall, its face flush with the wall, or surface-mounted where the entire box is exposed.

Places to look: garage , closet, pantry near the kitchen, basement , mudroom, hallway leading to garage or backyard.

One clue is to first find the electric service drop from the main power lines. Usually, your home’s service panel is located below and nearby, on the inside of your home.

Open the Door to the Service Panel

Open the door to the service panel by sliding the plastic switch to the side or up. Next, swing the door open. Use the inset plastic switch as a handle to pull the door open.

Locate Tripped Breaker

The handle of a tripped circuit breaker should be in the middle position—not left or right. Visually or by feel, locate any breaker handles that differ from the right or left positions:

• Tripped breakers : Tripped circuit breakers have a soft or springy feeling when you lightly press them leftward or rightward.
• Live/active breakers : Breakers that are not tripped are either firmly left or right (depending on which side of the box you're looking at).

Certain breakers, such as Eaton breakers , trip to the off position, not the middle position. Check manufacturer's instructions for your particular product.

Turn the Circuit Breaker Handle to OFF Position

Flip the circuit breaker handle to its firm OFF position, toward the outer edge of the service panel (away from the centerline).

Double and Tandem Breakers

Double pole breakers are double-wide breakers with wide handles. They are often used for dryer or oven circuits. Both sides of double pole breakers operate as one. Tandem breakers are two narrow breakers that share the space of one breaker. Each side operates individually.

Turn the Circuit Breaker Handle to ON Position

Flip the circuit breaker handle to its firm ON position, toward the centerline of the service panel. The handle should seat firmly in place and should make an audible click.

Test Circuit

Turn the device such as the light or A/C back on. If you believe the breaker tripped due to an overload, it’s best to turn on only one device at this time, not multiple devices. Also, choose a device with a lower power draw such as a light fixture.

• Remove some devices from the overloaded circuit and plug them into other circuits that aren’t drawing as much power.
• Avoid running many devices on the circuit at the same time. In a kitchen , for example, stage cooking activities that require power so that they happen in succession, not all at once.
• Install GFCI outlets so that the outlet shuts off before the entire circuit breaker shuts down in the case of a ground circuit. Just note that GFCI outlets are not circuit overload protection, but protection against dangerous ground faults.
• Replace old outlets, light fixtures, and switches which may create short circuits or trip breakers.
• Have an electrician separate hardwired devices that are drawing too much power from a single circuit. The electrician can move devices to another circuit or can set up an entirely new circuit to relieve the load.
• Replace the circuit breaker.

A qualified, licensed electrician is trained to detect the cause of tripped breakers and to fix those causes. If your problem of tripped circuit breakers is more than just an overloaded circuit, you may want to seek the help of an electrician. Unless you are an advanced do-it-yourselfer , it’s best to hire an electrician to wire up a new circuit breaker .

What You Need to Know

• A tripping circuit breaker could be a sign of an overloaded circuit, a short circuit, a ground fault, or a worn-out breaker.
• Homeowners will want to hire an electrician to determine the cause of the frequently tripping circuit breaker.
• Electricians may recommend replacing the circuit breaker, installing GFCI outlets, or rewiring part or all of the home.

Q: Every few hours—sometimes minutes!—my living room and one side of my kitchen lose electrical power. I’ll check the breaker panel and, sure enough, a circuit breaker has tripped…again. Should I call an electrician, or is there a simple DIY fix I can try first?

A: While it’s frustrating when a circuit breaker keeps tripping, they are important safety mechanisms. Designed to shut off the electrical current when something goes wrong, circuit breakers are one of the best ways of protecting a home from an electrical fire. “When a circuit breaker trips, typically it is because we use too much electricity, which causes it to overload and turn off,” says Christopher Haas, expert electrician and owner of Haas & Sons Electric in Millersville, Maryland. For those who need an electrical panels 101 refresher course or aren’t sure how to reset circuit breakers, each breaker has an on/off switch and controls a separate electrical circuit in the home. When a breaker trips, its switch automatically flips “off,” and it must be manually turned back on to restore electricity to the circuit. For those wondering, “Is it dangerous if a circuit breaker keeps tripping?” the answer is that it can be, depending on the source of the problem. An electrician can ultimately deal with the root issue, but a little sleuthing will reveal whether it’s something that’s easily remedied.

In many cases, the cause of a circuit breaking tripping is an overloaded circuit.

A circuit overloads when more electrical current is being drawn through the wires than they can handle, tripping the circuit breaker. If this happens, there may be a few additional signs:

• Buzzing noises coming from outlets
• Devices charging slowly
• Electrical outlets not working
• Flickering lights
• Scorch marks on outlets and light switches

If a circuit breaker keeps tripping in one room, homeowners can test for circuit overload by turning off all the switches in the affected area and unplugging all appliances and devices. After the breaker is flipped back on, the devices can be turned back on one at a time, with homeowners waiting a few minutes in between to see if the circuit remains on. If the breaker trips before all the appliances are turned on, the experiment can be repeated, this time turning them on in a different order. It may be necessary to do this several times to find out how many appliances can be operated at once before the circuit overloads.

“As a short-term solution, you can unplug unnecessary appliances to prevent tripping circuit breakers. You may still get some trips, but you can limit them by unplugging devices that you don’t need to use,” advises Dan Mock, vice president of operations at Mister Sparky , an electrical company with 90 locations in the U.S. The best long-term solution, however, is to pay an electrician for the cost to rewire the house and add additional circuits. The cost to replace an electrical panel is about $1,274 on average.

Other times, the issue may be caused by a short circuit.

A “short” circuit means that two wires that should not be coming into contact are inadvertently touching, triggering a sudden surge of electricity through the wires. A short can occur in an outlet, a switch, or within an appliance if wires are loose or have been chewed through by mice or pets. Some signs of a short circuit include:

• Popping sounds
• Discolored outlets or switches
• Burning smells

Testing to see if an appliance has a short is similar to testing for an overloaded circuit. When an appliance that has a short in its wiring is turned on, it will immediately trip the circuit. Homeowners can also try plugging it into an outlet in a different room. If the breaker for that room trips, there’s a short in the appliance (if it’s unclear what breaker goes to what room, the breaker can be identified with one of the best circuit breaker finders ). Electrical shorts can be a major fire hazard, so it’s a good idea to call a licensed electrician for this circuit breaker repair. It’s wise to stop using the outlet or appliance until a pro takes care of the problem.

Another potential cause of a circuit breaker tripping is a ground fault.

A ground fault occurs when the electricity running through a home’s wiring diverts from the wiring loop and travels to the ground, usually due to faulty wiring or water infiltration in an outlet or switch box. Water is a conductor, which is why walking through puddles is often listed as something not to do in a power outage in case of downed power lines. Once water makes contact with wires, electricity can jump from the wiring loop and follow the water trail. This creates a surge in electricity leading to a tripped circuit breaker. If a person comes in contact with the electricity that is on its way to the ground, this can result in electrocution. Homeowners may notice a few signs of a ground fault, including:

• Tripped GFCI (ground fault circuit interrupter) outlets;
• A burning smell coming from an outlet; and
• Lights flickering.

Newer electrical breakers have features designed to protect against the danger of ground faults. According to Haas, “Ground fault breakers sense electricity going to earth as opposed to going through the wires of the circuit. You’ll find [these] for bathrooms, kitchens, garages, exteriors, and basements.” GFCI outlets are another safety feature that shut off the electric current within a fraction of a second of sensing a ground fault.

If a ground fault is the problem, the cause of the errant water must be discovered and repaired, and any damaged wiring must also be replaced. It’s also a good idea to install GFCI outlets in rooms where water is commonly used. A GFCI outlet costs $210 on average.

Sometimes a bad or worn-out circuit breaker can be the culprit.

In some cases, the circuit breaker itself may be faulty. Breakers that are old, damaged, or were installed incorrectly may trip frequently for no apparent reason. Alternatively, faulty breakers may not trip when they are supposed to, leaving the home at risk of electrical fire. Some signs of a bad circuit breaker include:

• The circuit breaker getting hot and tripping frequently;
• The circuit breaker won’t reset;
• It has been over 10 years since the breaker was last serviced; and
• The breaker has scorch marks.

An important electrical safety tip to keep in mind is that resetting a breaker over and over again can cause what is called an arc flash, which is a small electrical explosion that can be deadly. If resetting the breaker once does not remedy the issue, it’s a good idea for the homeowner to hire an electrician near them who knows how to replace a circuit breaker safely. Mock warns, “Don’t take any chances with circuit breakers. Instead, call a licensed electrician who knows the safe ways to replace breaker boxes, upgrade circuits, and diagnose potential electrical problems in your home.” Wiring a breaker box is a job to leave to an experienced electrician.

A professional electrician can help determine the specific cause of a frequently tripping circuit breaker.

Most circuit breaker problems—aside from those explained in the sections above—will need to be inspected and addressed by a licensed electrician. According to the Electrical Safety Foundation International (ESFI) , each year “thousands of people in the United States are critically injured and electrocuted as a result of electrical fires, accidents, [or] electrocution in their own homes.” While homeowners may be tempted to save on electrician costs by attempting circuit breaker replacement or repair themselves, electrical work is not suitable for casual DIYers. “Yes, you have to pay, but you can save many hours of head-scratching by hiring an electrician. Electricians will also have all the right tools for diagnosing and repairing the circuit,” Haas adds. “Lastly, they will come with a warranty/guarantee should something arise, and they will typically return at no additional cost.”

Why does my fuse box keep tripping?

A tripped fuse box can occur at the most inconvenient moments. Fuses are a safety measure used in electric circuits. If there’s an electrical fault or excessive current flow, the fuse will break the circuit, causing your power to go out. You’ll find fuses located in the fuse box and inside electrical appliances or their plugs.

Fortunately, it’s usually pretty easy to identify the root of a tripped fuse and reset a trip switch yourself. Don’t be left in the dark! Follow our helpful guide and find all you need to know about how to identify and fix fuse box-related issues.

How does a trip switch fuse box work?

Modern fuse boxes consist of trip switches that turn off a home’s electricity as a failsafe. This occurs when there’s an electrical fault or too much power flows through a circuit.

There are two types of fuse boxes – modern trip switch fuse boxes and traditional fuse boxes, which are more common in older homes. These have fuse wires that need replacing when they break. Today, in most homes, trip switch fuse boxes don’t use traditional fuses. Instead, they use safety switches like circuit breakers or RCDs (residual current devices).

Looking to learn more about fuse boxes? Find out more with our fuse box guide .

Where can I find my fuse box?

You’ll usually find your fuse box in a utility room, porch, garage or cupboard under the stairs. Essentially, it should be in an accessible location so that if your lights go out, you can access it safely.

Why has my fuse box tripped?

Are your sockets not working? Have your lights gone out? You’ve likely tripped a fuse switch. The easiest way to tell is by checking your fuse box to see if any electric breaker switches have flipped downwards. If they have, you’ve either overloaded a circuit with too many electrical appliances, or one of those electrical appliances is faulty. Before you flip the switch and turn your power back on, you must work out what’s causing the problem.

Overloaded Circuit

Electrical circuits can only handle a certain amount of electricity. If you’re boiling your kettle, using your toaster, charging your phone, watching TV and running your dishwasher all on one circuit, you could overload it. This causes the fuse switch to blow, resulting in a tripped fuse.

Extension leads are often the source of the problem. Even though they have multiple sockets, you shouldn’t use them all at once. Doing so puts excessive pressure on a circuit and may be why your electricity keeps tripping.

Faulty Electrical Appliance

A faulty electrical appliance can force a tripped fuse. There might be a problem with the wiring or the appliance may be old and worn out. Can’t work out which appliance is the culprit? Look at your fuse box – the switches might be labelled, helping you identify the location of the faulty circuit. When you know the location, try to remember which device you plugged in last – this is often the source.

If your box isn’t labelled or you can’t narrow down the problem, there’s only one solution. Unplug every device in your home, reset the switch (more on this below) and plug them back in, one at a time. It’s time-consuming, but should help you identify the problem.

Here’s a tip: the cause will likely be the last appliance or light fixture you used. Trip switches are sensitive, so they’ll kick into action as soon as there’s an issue.

How to fix a tripped fuse box

Once you’ve identified the cause, you can reset the fuse box. Do not use any faulty appliances until you’ve checked them. Unless you know what you’re doing, it’s best not to carry out electrical repairs yourself. Instead, get in touch with a qualified electrician. Or, if an appliance is new and under warranty you can return it. With proof of purchase, you should be able to get a refund or a replacement.

Reset your fuse switch

Today, most homes have trip switch fuse boxes installed with electrical fuse breakers. These switches flip down when they need to trip the electrics.

• They’re straightforward to reset – all you need to do is switch them back into the ‘on’ position.
• If you have attempted to reset your fuse switch, but it keeps tripping, there’s likely a problem with one of your appliances or sockets.
• If none of your electric trip switches have moved, one of the RCD switches has probably tripped. Make sure they’re turned on too.

Resetting older fuse boxes

Older properties may still feature a traditional fuse box containing fuse sockets. Each fuse socket contains a piece of wire that will physically snap or burn to break a circuit. Replacing fuse wire is relatively straightforward. Find out how to replace a blown fuse .

What if my fuse box keeps tripping?

If you can’t work out why your fuse switches keep tripping, there could be a problem with the fuse box’s wiring. Faulty electrics can be dangerous, and even with precautionary measures like RCD switches in place, it’s not worth risking your safety. Rather than looking into the problem yourself, we recommend getting in touch with a qualified electrician. They will know what they’re looking for and can fix the problem on your behalf – swiftly and safely.
