First of all, is the breaker bad? How did you test it? Breakers don't usually go bad, very seldom. A simple test is to use a meter and check for voltage at the output terminal. Is it tripping or what is going on? Unhook the wire feeding off the breaker, then reset it. If it holds, it's probably fine. You can use an ohm meter and check for 0 ohms through the breaker too (with it unhooked and out of panel)

To test a circuit breaker you should set the multimeter to "Volts AC" and touch the prongs to the breaker's terminal screw and a ground. If there is no power, the breaker is faulty and requires replacement.

I have a 40 amp gfi circuit breaker for my hot tub and want to know how to test it to ensure that it is not the breaker that is faulty as they are very expensive and from my understanding they cannot be returned for a refund after purchase

Outlets do not work, circuit tester says Hot/ground reverse but all connections appear correct, circuit is on an arc arrest breaker.


Move wires to different breaker with same amp rating?
Try different tester?

Test wiring box-by-box to locate the reversed connection.

Check each box for Hot and neutral:

The prcblem i have is i have no power in one bedroom, but there are no curcuit breakers that are tripped. so how can you test a breaker other than resetting the breaker. also we have no gfi outlets or gfi...


I don't know how technical you are so here are a few easy tests you can try:

plug a known, working lamp into each plug of the receptacle (top and bottom). This minimizes other potential issues.
Switch each circuit breaker FULLY off and then, Fully on. Yes, it is tedious but sometimes, breakers trip and it doesn't always show.
Still not working? Open up the cover plate and look at the contacts. You should have a black wire going to a gold colored screw and a white wire going to the other side, silver colored screw.

The best test you can conduct is using a simple voltmeter (AC) to test if you are getting voltage to the outlet. No AC Voltage? Try going to the known circuit breaker and measure the voltage coming from the known breaker while the other lead is on your neutral bus. Of course, if you aren't experienced with electricity, I recommend you get a licensed electrician to troubleshoot the issue.

As well, I know you mentioned that you tried resetting breakers but with a load on the circuit and someone else verifying it for you, you may just get lucky. More than likely, you will either encounter a faulty outlet, faulty wiring or a faulty breaker.

Is there a way to safely load test a breaker to make sure it will trip correctly


Short of using expensive load test equipment about all one can do is purposely overload the circuit. Usually 2 heavy loads will do it for a 20 amp circuit, such as 2 microwaves or a toaster oven. Turn both on at the same time and it won't take long for the breaker to trip. If the breaker trips on overload it will trip on short circuit, so, DO NOT purposely short circuit the breaker as that is a lot of unneccessary wear and tear on the breaker.

Cutler Hammer 20 Arc Fault breaker for bedroom outlets will not reset after activating test switch.


The circuit breaker must be turned to the "off" position first from the middle position, and then to the "on" position. The cutler hammer arc breakers carry a lifetime warranty so if it will not reset you may want to contact the manufacture.

Bathtub pump totally dead, pump ran dry for 10 sec, is there circuit breakers on pump motors, switch or is it the motor shot. any way to test motor with removing it?


Normally pump motors are connected on a separate
circuit with its own circuit breaker. At your house there is always a electrical control panel housing several circuit breakers for lights, power outlets, range, aircon, motors, etc...Find a tripped off breaker and reset it. To reset the circuit breaker is to switch it to off position and back to on position. Better still you may reset all the circuit breakers except the main
circuit breaker (biggest amp rating).
After resetting the circuit breakers, try to switch your
bathtub pump on, (to test it, if it is still okey). Other-
wise, your motor is damaged and you got to have the
motor rewinded, to be operational.

I just bought a new Sperry circuit breaker finder and I can test the transmitter& receiver, but it doesn't respond to the breakers in any way. I tried different outlets, I may be doing something wrong...


Hello

Is there a battery in the scanner? It takes times to clear out the breakers and find the right one. Be patient. It could be defective? Start on the top of the breakers on either side and vertically slide it down to the bottom then up the other side. Make sure it touches the breakers just to the left or right of the switches on each breaker. Again, it takes up to a minute to find the right. Once in awhile it chooses the wrong one.
