Other Important Factors to Consider
What is a Circuit Breaker Finder?
This non-contact tool is designed explicitly for professionals and DIY enthusiasts who are working on electrical systems. If you’re working on a breaker panel with no proper labels, you can use this tool instead of manually switching off each circuit to find the correct one.
This is important, especially if you’re working with systems that cannot be turned off – like computer servers, security feeds, and even life support.
You have to note, though, that although the transmitter of the circuit breaker finder emits a strong signal that you can use the receiver to trace the circuit, it is not a wire tracer tool. There are specific tools that are specifically used to trace wiring, which you should use.
How Does It Work?
Most circuit breaker finders work by having a transmitter and receiver. The transmitter would plug into the outlet or bulb receptacle. In cases that you’re working with live wires, you can use the optional alligator clip accessory.
The transmitter would then utilize that electricity in the energized wire to send a signal through the circuit. You would then use the receiver on the breaker panel to detect which circuit breaker switch the signal emanates.
To improve accuracy, you typically have to calibrate the receiver on the breaker panel by running it over through all the switches once or twice. There are also some receivers with manual calibration, so you can start searching for the signal by manually adjusting the device’s sensitivity.
What are the Different Types of Circuit Breaker Finders?
A circuit breaker locator has two primary types: automatic devices and manual devices. The automatic finders have a built-in signal processing unit that will adjust its sensitivity based on the signals it receives during the calibration phase.
On the other hand, the manual ones have a built-in sensitivity switch for the proper settings.
The automatic models are usually more comfortable to use, requiring little experience. Still, they may take a little bit longer than the manual mode as you have to calibrate them before each use. Although harder to learn at the start, the manual devices can be faster to work with, mostly if the operator is used to it.
Why Do You Need a Circuit Breaker Finder?
Circuit breaker finders are handy tools, as they let you know the correct breaker that a particular receptacle is connected to. This is crucial for safety, as it is dangerous to work on an energized circuit.
These machines will also save you time and effort because you no longer have to figure out if you’re toggling the correct breaker manually. With a finding device, you won’t have to switch off a breaker and then go back to the plug that you’re checking just to see if it’s the correct one.
Several circuit breaker finders also have built-in GFCI testers. This is an essential feature as it can test if the GFCI in the outlet is working and properly configured. If you’re an electrician or electrical professional, you cannot live without one of these tools.
Frequently Asked Questions
What are the Most Trusted Circuit Breaker Finder Brands?
Some of the well-known brands are the Greenlee Circuit Breaker Finder and the Fluke Circuit Breaker Finder. They are trusted by many professionals but also come at a steep price.
If you’re looking for a more value for money model, I would recommend the Sperry Instruments CS61200P. Its unique build makes it very convenient to use. Sperry Instruments itself is a trusted brand, not just in circuit breaker finders but also in other instruments.
You can check other electrical circuit tracer reviews. I’m sure that you’ll find many that would recommend the same or similar brands.
How Do I Find a Circuit Breaker?
Most circuit breakers banks are located inside the house, in a recessed metal box. They are typically found in the kitchen, garage, pantry, or basement – although they can also be outside of the structure at times.
If you don’t have a circuit breaker finder, the only way of finding the correct breaker is to do it manually – plug in an appliance on the outlet that you’re checking and then switch off the breakers in the bank one by one. Keep on doing this until you find the correct breaker.
It is a tedious task that could take up to half an hour if you’re working on a large structure. That is why circuit breaker finders have been developed. With this tool, the correct circuit will only take minutes to find.
How Do I Find a Circuit Breaker Without Power?
The most reliable way to find a powerless circuit breaker is to use a wire tracer tool. These are specifically used for those applications and will work whether the circuit has power or not. These are typically pricey, though, and may not be an option if you’re using it only once.
If you’re stumped with one circuit, don’t try to do it yourself. These energized wiring on open circuits could be dangerous, and I recommend hiring an electrician who will do the job safely and correctly.
Where Can I Buy?
You can read through circuit breaker finder reviews, which typically have links to the products that they’re reviewing. There are many buying guides out there which you can rely on. Some of the websites you visit may earn on affiliate sales, but they will still generate reliable reviews.
Additionally, while you can purchase these off Amazon-com, I usually prefer to buy directly from the local hardware retail store’s website that I buy from, but that’s just my preference.
Alternatively, some manufacturers allow you to purchase directly from their website while others recommend a retailer near you. Or you could head to a retail store nearby if you want to see the unit for yourself before making the purchase.
What is a GFCI?
A ground fault circuit interrupter or residual current device (RCD) is a type of circuit breaker that shuts off electrical power. While typical circuit breakers trip when the current is high – like 10 to 20 amps, the GFCI will trip on differences as low as 0.005 amps.
The circuit breakers in the breaker bank are designed to protect against overheating and fires. On the other hand, GFCIs, which are usually seen as the red and black buttons on outlets, are designed to protect humans from electrocution.
Circuit breaker finders and testers are simple devices that will save you a lot of time and money. With this tool, you no longer have to manually switch off each breaker switch only to find the correct circuit breaker. This is also crucial if you’re working with circuits with systems that rely on constant power – like PC and internet servers, camera and security systems, hospital, and life support systems, among others.
This also improves your safety, as you can be sure that if you’re working on an electrical circuit, it has been shut off completely and will not electrocute you.
