how to locate bad breaker

mswitzer · #1 Jun 10, 2006, 07:25 PM

I have a bad breaker on one of central ac units. However there are no labels on the panel to identify which breaker goes to what. How do I tell which breaker goes to the ac unit that has no power. I installed a new switch in the attic and measured the amps on the wires coming from the breaker while I had the switch off and got no voltage. I appreciate any help.

thanks,
Mark

Take the panel cover off and test the breakers, which should all be "on". You'll need a voltage tester or a "wiggie". Any breaker that is on but does not give power to the wire should be considered no good.
