Circuit breakers are amazing devices that protect your appliances and gadgets from receiving too much current. The sockets you plug your appliances and gadgets to give out a constant voltage of either 110V or 220V. The formula for power is:

Power = Voltage * Current

If, say, your power sockets have a voltage rating of 110V and we plug a hairdryer with a power rating of 1000W and a gaming computer with a power rating of 3000W to an extension cord that can only handle 20A of current, the excess ~17A current overheats and melts or burns the extension cord.

Circuit breakers are built to automatically cut off the current when they reach a defined threshold.

Why Buy a Circuit Breaker Finder?

It’s rather easy to know which circuit breaker has been tripped because the switch would be in the ‘off’ position.

There are, however, some cases wherein you’re not trying to restart a tripped circuit breaker; you may just be trying to do some electrical work that requires you to turn off a circuit.

Because circuit breakers are part of this circuit, by turning one of them off you effectively cut off power to certain outlets. That being said, you’ll find that a circuit breaker finder comes in quite handy as it lets you find exactly the circuit breaker that corresponds to a specific power outlet.


The factors for consideration when getting circuit breakers are different from the factors of consideration when you are getting refrigerant leak detectors.

Purpose of Circuit Breaker

A circuit breaker finder is also used with circuit breakers and is used to locate the position of a circuit in a circuit breaker box. You need to be aware and mindful of how you are going to use a circuit breaker finder before you buy one. You must also be familiar with its method of use.

If you are not sure about any one of these, you can talk to an electrician and have him do the job for you, to avoid any safety risks.


You do not want your product to wear out with time and your money to go to waste. To avoid that from happening, make sure you consider the factor of durability before buying your circuit breaker finder.

Even though these usually do not wear out with time, but buying something cheap in quality will increase the odds of you losing the freshness and feel of the product over time. For tools like miter saw blades and drill bit sharpeners, the durability should always be a factor of consideration


Circuit breaker finders are used for different purposes.

So make sure you know what you want to use it for, to avoid wasting your money on something that is not what you need and coming back home to regret the decision you made.

This, combined with the budget planning, is going to help you come home with the best product you could afford.

Circuit Outlet

The circuit outlets that circuit breaker finders are compatible with also vary from product to product. So take a look at the power outlets inside your home, and get a circuit breaker finder that runs by your needs.


Especially in larger homes, it’s important to consider the maximum distance possible between the transmitter and receiver. Some circuit breaker finders will indicate this while some leave it up to the user to find out for himself.

Some can go or as far as 1000 ft. whereas some can go only up to 100 ft. You’ll want to choose one that has a range that includes the distance from your circuit breaker to the farthest outlet in your home.


To date, there’s no single circuit breaker finder that can be considered to be the best. Circuit finder reviews will often contain mixed responses, from devices coming up with a lot of false positives to devices giving amazingly accurate readings.

This is because even the circuit breaker finders easily provide inaccurate readings when there are too many wires in an area. In this case, you’ll find that anecdotal reviews may be more useful than purely technical reviews. Another tool that requires a high level of accuracy to deliver perfect jobs is the circular saw blade.

Build Quality

High-quality circuit breaker finders should have sturdy ground pongs, receptacle testers, and other parts that you’ll commonly have to plug in or pass a current through quite a lot of times.

A lot of users have complained about one or two of these parts breaking off at the most inconvenient times. That being said, you don’t want to cut corners when it comes to building quality.
