They are usually installed in your electrical service panel to help protect your home appliances and other electrical systems from overloads. You can also use them as convenient shut-off points for electrical circuits. This way, you can easily shut off power whenever you need to make repairs or upgrades to a circuit.

As you read on, you will find some of the factors to consider before buying a circuit breaker finder. You should also read through the specification and comparison table to know which of the product suits your budget.

Lastly, I’ll leave you with my final thoughts based on the above-selected products.

So, without wasting much time, let’s get down to business.

Features of A Circuit Breaker Finder

A circuit breaker finder is a tool designed to help electricians and DIY enthusiasts locate circuit breakers in electrical panels quickly and easily. Some of the features of a typical circuit breaker finder include:


The transmitter is part of the circuit breaker finder that plugs into the outlet or attaches to the wires. It sends a signal down the circuit to help locate the corresponding circuit breaker.

The transmitter typically has multiple settings that allow it to work with different types of circuits and wiring configurations.

Some transmitters also have additional features, such as the ability to adjust the signal strength or to test for the presence of live wires.

Overall, the transmitter is an essential component of a circuit breaker finder, as it allows the device to accurately and quickly locate the correct circuit breaker in an electrical panel.


The receiver is used to locate the signal sent by the transmitter. It is typically a handheld device that is used to scan the circuit breaker panel. When the receiver detects the signal, it indicates which circuit breaker controls the electrical outlet or fixture.

Also, the receiver has a set of LED lights or an LCD display that indicates the strength of the signal, allowing the user to pinpoint the location of the circuit breaker more accurately. Some models may also have an audible alert or vibration feature to help the user locate the breaker.

Overall, the receiver plays a critical role in the circuit breaker finder by detecting and interpreting the signal transmitted by the transmitter, thus, helping the user quickly and easily identify the circuit breaker associated with a specific outlet or electrical device.

LED Lights

LED lights in a circuit breaker finder serve to indicate the presence of a live electrical signal. When the circuit breaker finder is connected to an outlet or electrical circuit, the LED lights will light up to indicate that a live electrical signal is present.

They are often used to provide a visual indication that the transmitter is sending a signal and that the receiver is detecting it.

The lights can help the user determine whether the transmitter and receiver are working properly, and can also help identify which circuit breaker corresponds to the outlet being tested.

Audible Tone

Many circuit breaker finders also have an audible tone that sounds when the correct breaker is located. This is helpful in noisy environments or when the user is visually impaired.

When a circuit breaker finder is used, it sends a signal through the wiring in the building, which is picked up by a receiver. As the receiver gets closer to the correct circuit breaker, the audible tone gets louder and more distinct, indicating that the correct breaker has been found.

The audible tone is a useful feature in a circuit breaker finder because it allows you to quickly and easily locate the correct circuit breaker without having to visually trace the wiring. This can save time and effort, especially in large or complex electrical panels.

Sensitivity Adjustment

The sensitivity adjustment in the circuit breaker finder allows the user to set the level of sensitivity of the device to detect the signal in the electrical wire.

By adjusting the sensitivity, the user can ensure that the device can accurately detect the presence of a live electrical signal without being overly sensitive and detecting signals from other nearby wires or sources.

This makes it easier for the user to locate the correct circuit breaker or fuse and avoid accidentally tripping other breakers in the process.

Circuit Tracing

Some advanced circuit breaker finders have the ability to trace circuits. This allows the user to follow the path of a circuit through walls and ceilings to identify the location of outlets, switches, and other electrical components.

By identifying the correct circuit breaker, you can easily and safely turn off power to a specific circuit for repairs or maintenance. You won’t have to stand there with the tool in your hand thinking of what to do.


Circuit breaker finders are designed to work with a variety of electrical panels and breakers, so it is essential to check the product’s compatibility before purchasing.

Things To Look Out For When Buying A Circuit Breaker Finder

When buying a circuit breaker finder, there are several factors you should consider:

Type of Circuit Breaker

There are two main types of circuit breaker finders, namely outlet testers and electronic finders.

Outlet testers are the more basic type, and they work by simply plugging into an outlet and displaying whether the circuit is live or not.

Electronic finders, on the other hand, use advanced technologies to trace the circuitry and identify the location of the circuit breaker.


The circuit breaker finder’s accuracy is an important factor to consider. A reliable circuit breaker finder should be able to accurately identify the circuit breaker’s location and avoid false readings.


The circuit breaker finder’s sensitivity refers to its ability to detect a signal. The more sensitive the device, the better it can detect the signal and locate the breaker. However, if the device is too sensitive, it can lead to false readings.

Ease of Use

The circuit breaker finder should be easy to use, even for a novice. It should come with clear instructions and have a simple interface.

In that case, it is important to follow all safety precautions and manufacturer’s instructions when using a circuit breaker finder.

However, if you are unsure about how to use the tool, it is recommended that you consult a licensed electrician.


The circuit breaker finder should be durable enough to withstand frequent use and occasional drops or bumps.

A well-built and sturdy device will last longer and save you money in the long run.

Additional Features

Some circuit breaker finders come with additional features, such as built-in flashlights, audible alarms, and automatic shut-off. Consider these features and decide whether they are essential or not.


Finally, consider the price of the circuit breaker finder. Compare prices among different brands and models to find one that fits your budget without compromising on quality. Remember that a higher-priced model does not always mean better quality.
