Frequently Asked Questions
How to locate the correct circuit breaker?
Do circuit breaker finders work?
Yes, a circuit breaker finder does work. All you need to do is that, use the electronic receiver which is paired with the transmitter at the breaker box.
As you pass the receiver over the circuit breaker which carries the electronic signal from the transmitter, the receiver starts flashing and beeping rapidly.
Its working principle is as simple as that.
What is a digital circuit breaker finder?
A digital circuit breaker finder is a device that is used to locate the position of the right circuit breaker in a panel.
It locates the circuit breaker that corresponds to a fixture or any electronic outlet.
The tester has two parts, the receiver which is used to scan the panel, to locate the correct breaker, and a transmitter.
The transmitter connects to the fixture or current outlet.
How do you trip a circuit breaker?
To trip a circuit breaker, you need to follow three steps.
The first step is plugging the portable appliance into an outlet that the circuit breaker needs to serve. The second step is to open the front cover of the main breaker box.
You need to turn off the circuit breaker that is powering the electrical circuit. It is quite easy to find because many breaker boxes feature a list of circuits alongside which the corresponding circuit breaker number is mentioned.
The last step is to turn the switch off, which is located on the front of the circuit breaker. You need to go back to check if the appliance that was previously on is now off.
If it is still on, it means you have tripped the wrong circuit breaker.
Can I use a circuit breaker as an on/off switch?
Yes, a circuit breaker can be used as an on-off switch. However, the duration and frequency of such use are limited.
Circuit breakers being used to turn the lights on and off is not a very good idea. Breakers are specifically meant to protect your wiring, and they are only to be used to disconnect your circuit in case something goes wrong.
If you routinely use them to turn your switches on and off, it will reduce the life of the breaker.
How do I know which outlets are on the same circuit?
To check which outlets are on the same circuit, you need to turn the breaker off, which is feeding power into an outlet, and then check if the other outlets still have power.
For that, you need to get a lamp and plug it into any outlet that you need to check. Turn that lamp on. Then go to the electrical panel, and turn the breaker (which you reckon controls the panel) off.
Then check to see if the lamp has been turned off to verify if you have turned the correct breaker off.
Once the breaker that is controlling the outlet of the lamp is off, and all other breakers are on, the outlets with no power are on the same circuit as the outlet of the lamp.
Plug the lamp in any other outlet and repeat the same procedure to determine if the outlet is on the same circuit.
How does a circuit tracer work?
A tracer is used to trace the path of a circuit. A breaker finder will only work on the energized circuits.
Tracer has three parts, receiver, transmitter, and probe. The circuit tracer deducts the use of physical contact with the electrical equipment, which is way safer for the people operating the system.
There is a wide range of them available in the market, so make sure you find the best circuit breaker locator out there.
What is circuit tracing?
Circuit tracing refers to the process of tracing the path of a circuit. A tracer has a transmitter and a receiver.
The transmitter generates a unique signal on to the circuit, which is to be traced. The receiver is meant to detect this unique signal when it is placed in a proper orientation to the wires that are being traced.
The receiver then indicates a numerical value which will increase as the signals become stronger.
What causes a breaker to trip repeatedly?
A circuit breaker will trip if any of these three situations are encountered.
One of the main reasons circuit trips is an overload. It happens when you make a breaker provide more electricity than its capacity. This will cause overheating and in turn, causing the breaker to trip.
The second reason is a short circuit, which proves to be more dangerous than the first reason. It happens when a neutral wire comes in contact with a hot wire, causing the current to overflow in a circuit, tripping the breaker.
Last reason is the ground fault surges, which are almost similar to short circuits. They happen when the ground wire comes in contact with a hot wire, causing the circuit to overflow with current, and tripping the circuit breaker.
Can a circuit breaker fail without tripping?
Yes, a circuit breaker can fail without tripping. This happens when the circuit breaker wears out.
However, it is quite infrequent of circuit breakers to go bad due to wearing out, so we can say that the main reason why circuit breakers go bad is due to tripping.
What happens if a breaker doesn’t trip?
If the breaker does not trip immediately, it means that the circuit is probably overloaded, which indicates that there is more electricity flowing through the circuit than what it is rated for.
If you want to fix this, you need to move some electrical devices to some other circuit.
How many times can a circuit breaker trip?
A circuit breaker can trip only once. If it trips more than once, you need to replace it. Make sure you call an experienced electrician to do so.
Whether it is due to wearing out or any other reason, a circuit breaker needs to be replaced after it trips once.
Do circuit breakers get weak?
The main reason that a circuit breaker can fail apart from tripping is the breaker wearing out. However, it is quite uncommon for it to wear out with time.
So it can be said that circuit breakers will not get weak with time and will not need to be changed unless they trip.

Is a circuit breaker finder necessary?
Hi, Martin
To be very honest, it is not necessary; however, it does help a lot if you are not that good with circuits.
I wanted a professional circuit breaker finder; however, my budget is limited, which is why I have chosen Meterk RJ11 Wire Tracker. Is it worth it?
Hi, Willie
Congratulations on your perfect pick. I would like to assure you that you have made the best choice possible! Glad to be of help.
I spent a very long time researching this Klein ET300 in comparison to the Ideal unit and the Amprobe unit. Each has some positives and negatives but I decided to go with this unit for a few reasons. I was right, this unit works better than I expected it would be. This tool is awesome, I have had it for close to 2 years and have used it dozens of times.
One of my colleagues has recently switched to this Klein ET300 after my review and he’s also very pleased with this product.
