10 Best Circuit Breaker Finders 2023[Our Top Picks]

A circuit breaker finder is a device that helps people figure out the location of their circuit breakers to avoid tripping them. These are usually found near the electrical panel, which makes them difficult to find.

Thankfully, there’s now an easier way. You won’t have to worry about not finding a faulty breaker again! Instead, it’s easy to test it out before leaving the house or heading into an unknown building.

Using an electric breaker finder device will also help you avoid costly repairs by alerting you to problems before they become too serious.

Most circuit breaker finders are easy to use and will locate any faulty breakers in your house quickly. Furthermore, it’s a must-have for anyone who wants to keep their family safe at all times.

Today, I’ll share a top 10 list of the best circuit breaker finders and share which things you should consider before buying one.

So let’s get started.

What to Look for When Buying Circuit Breaker Finders

It’s not easy to find a good quality one. There are so many models available, and it’s only natural to feel overwhelmed at first glance.

So when buying one, read some of the things you should look for to ensure you get a suitable model.


A breaker finder tool should have a high enough rating. The higher the amps, the better it’ll be to find your breaker. It’ll not be able to detect hard-to-reach breakers if the rating is too low.

In short, this is the 1st thing you need to look for when buying one.


A finder should be easy enough to use. Also, controls and features should be easy to understand so that anyone can utilize the device without technical training.

You should not purchase a difficult one. Instead, look for finders with one-touch controls, non-slip grips, and brightly colored buttons.


For best results, you should purchase a UL-certified circuit breaker detector. UL certification means the breakers have been tested and verified to meet safety standards.

The UL seal is not just a standard for breakers but also a guarantee that products for your home are safe.

GFCI Testing Capability

Remember that a circuit finder should be able to test GFCIs too. Since most households have GFCI outlets installed, so it’s necessary to get a breaker finder to try them.

You should choose a breaker finder that can detect GFCIs and highlight them on the device’s display.

LED light & Display

Try to buy a breaker finder with a bright LED light and a large display. A breaker finder with a small display will be tough to see, and a light that is too dim will be hard to use.

So it’s best to go for one with a bright LED and large-sized display for convenience and ease of reading.

Does a circuit breaker finder work with fuses?

Yes, it works on any home’s electrical system: fuses, breakers, or ground fault circuit interrupters (GFCI).

Will a circuit breaker finder work with a dead outlet?

No, it only works on live outlets. The unit will not work with any circuit that has been turned off.

How do you trace circuit breakers?

When an electrical circuit breaker is tripped or fails, you can often follow it directly to its power source. Unfortunately, many modern homes run several circuits from one electrical box, so it isn’t always easy to identify the circuit breaker that controls a specific outlet.

Can you use a circuit breaker finder on an extension?

No, an extension cord or power strip does not contain a circuit breaker. So it’ll not work on extension cords because it isn’t possible to trip the unit itself.

How do I find a circuit breaker without power?

If you’re trying to locate a circuit breaker that is no longer receiving electricity, the device will not sense it. This is because the circuit breaker finder only works when a circuit is powered on.


Sometimes finding a circuit breaker for a specific device for your home is a challenge. It’s not easy to know which circuit breaker controls what, and you cannot just flip every switch in the house until one of them works.

Moreover, most people have no idea how many amps they are using or how much power their appliances consume.

A circuit breaker finder will show you exactly where to look for your problem. It’ll also show you how many amps each appliance is using so that you can make any necessary adjustments.

If you want to save money on your electric bill and protect yourself from electrical fires simultaneously, this will be an excellent tool for you!
