10 best circuit breaker testers
Circuit breaker testers are essential tools used in the field of electrical maintenance and testing. They are designed to ensure the proper functioning of circuit breakers, which are critical components of electrical distribution systems. Here's what you need to know about circuit breaker testers:
Purpose: Circuit breaker testers are used to evaluate the performance and reliability of circuit breakers, which are safety devices designed to protect electrical circuits from overloads and short circuits. These testers help ensure that circuit breakers can operate as intended when needed.
Testing Procedures: Circuit breaker testers perform various tests to assess a breaker's functionality. These tests include:
Timing Tests: Circuit breakers must open and close within specific time intervals. Timing tests assess whether a breaker operates within the specified time limits, ensuring it can interrupt the circuit when necessary.
Contact Resistance Tests: These tests measure the resistance at the breaker's contacts to identify any issues with the electrical connections, which can affect the breaker's performance.
Minimum Trip Voltage Tests: These tests determine the minimum voltage required to trip the circuit breaker reliably, ensuring it can protect the circuit under various conditions.
Overload and Short-Circuit Tests: Circuit breaker testers can simulate overload and short-circuit conditions to evaluate the breaker's response and performance under extreme situations.
Safety: Circuit breaker testing can be a hazardous activity, as it involves manipulating electrical components. Safety precautions, such as wearing appropriate personal protective equipment (PPE) and following established safety procedures, are crucial when using these testers.
Types of Circuit Breaker Testers: There are various types of circuit breaker testers available, including portable handheld testers and more sophisticated, computer-controlled test systems. The choice of tester depends on the specific requirements of the testing task.
Calibration and Maintenance: Circuit breaker testers need to be regularly calibrated and maintained to ensure accurate results. Calibration ensures that the tester provides reliable measurements.
Applications: Circuit breaker testers are commonly used in industries such as electrical utilities, manufacturing, and facility maintenance. They are used during routine maintenance, commissioning of new equipment, and troubleshooting faulty circuit breakers.
Reporting: After conducting tests, circuit breaker testers often generate reports that provide detailed information about the breaker's performance.These reports can be used for compliance documentation and maintenance records.
In summary, circuit breaker testers are essential tools for maintaining the reliability and safety of electrical distribution systems. They help ensure that circuit breakers function correctly and protect electrical circuits from overloads and faults. Proper testing and maintenance of circuit breakers are crucial for the safety and reliability of electrical systems.

User questions & answers
Question: | Can this trace a wire routing through the wall |
Answer: | It's configured for 120 though you'd have to read the specs to see a out 240. |
Question: | I have outlets wired in series: some NM. some metal-shielded. Can I detect signal in accessible wires "halfway" to the breaker to confirm route |
Answer: | That would be a bit more difficult. You would have to replace the bulb with one of those socket adapters that have the socket and outlets to plug in cords. I think that would work to find the right breaker since you could plug in that part of the detector. |
Question: | Will this product detect a bootleg ground |
Answer: | No, the circuit must have power to generate a signal that is traceable to the breaker panel. |
Question: | Can you use this to trace the outlet to its circuit breaker if the circuit breaker is damaged or off |
Answer: | There is nothing on the product to indicate that it is. The item is UL approved, sturdy, and works very well. You can find Sperry on Facebook and ask your question there. |

User questions & answers
Question: | Will this product be able to identify more than which outlets are related to a particular circuit; such as light switches, oven vent fans, etc |
Answer: | That 69411 catalog number is for the: "Circuit Breaker Finder Accessory Kit". That was available when I purchased mine but I don't know about now with this virus problem. I do not believe that amazon will answer your question in this manor. Probably the only way to find out from Amazon is to just try ordering it and see what your response will be. |
Question: | I have 220vac outlets, if the remote plug-in unit only works with 110vac can I go one side to ground and simulate a 110 circuit to find each breaker |
Answer: | I am not sure but I would suspect code for high voltage lines should be properly marked for identification. |
Question: | Does the power have to be on for the tester to work |
Answer: | I don't know but im sure that the circuit wiring configuration along with the load center configuration will effect it's operating range. There are several variables that can effect the tester's operation. |
Question: | Does it work for higher voltage like 220 v |
Answer: | Does not have a sensitivity wheel, I’ve had no issues with it usually within one breaker its spot on. Just have to hit reset if u skip over the correct one to clear memory before re scanning |

User questions & answers
Question: | Btw amazon photo shows 2 pack logo! even though you only get one set |
Answer: | NO! It is, and the specs say, it is for 120vac. House wiring is 120vac. If you are wondering about 220vac, then you are probably thinking (giving you the latitude here, that you know about 220vac house service (which can be either 2 or 3 phase). Only one of those phases is used within the normal house receptacles. Even if you just look at the regular 3 prong plug between the two larger devices, you will see that is is the expected 120vac plug. A 220vac plug looks quite a lot different. Anyone trying to diagnose the (2 or 3) multi-phase service would typically just diagnose one phase at a time. So this *could* be used to troubleshoot 220vac - AS LONG AS you are just diagnosing *one phase at a time*. If you don't have clue as to what I have just spoken about then leave it alone! You are, in the least, going to waste your money, or burn out something, and at worst, possibly burn your house down. Get an electrician to help you out. |
Question: | Does anyone else have issues with the sensitivity of this unit? I can't pinpoint a breaker, just a range of at least 5-6 push it to max |
Answer: | Yes! Do this at your own risk, obviously. For some of the circuits in my house, the signal from the transmitter was too weak for the detector to pick it up through the breaker switch itself, but scanning the wires always worked. |
Question: | Will this work on220 volt |
Answer: | If you just need to test for continuity then you can put an rj45 jack on each end and tone one end and test the other you can see if you have continuity |
Question: | If you take the breaker plate off can you get a better indication on a specific wire going into a breaker |
Answer: | you will still have to connect the generator to the cable somewhere. since they are low voltage it should work. |
