Default How do you know a new circuit breaker is protecting the circuit properly?
I am changing a 50-amp breaker to a 30-amp one to install an oven that
draws less current than the old one did. I have seen information here
about testing a bad circuit breaker, but how do you test a good one? In
other words, if I install a new breaker, how do I know it will trip if
the load exceeds 30 amps?
