I have a portable 120 Volt generator intended for use by contractors, that
has a Ground Fault Circuit Interrupter (GFCI) duplex outlet. It also has
an L5-30 twist-lock outlet that is not connected to the GFCI.
Using the twist-lock outlet for my load tests, the GFCI outlet will
occasionally trip with nothing plugged into it. I assume the generator's
vibration is causing it to trip.
My question: Is this a common problem with generators, or is my GFCI
outlet just defective? If I install a new one, is it likely to exhibit
the same spurious tripping?
Having tripped them myself when making dumb mistakes, I can appreciate
their value. However, frequent spurious tripping is very inconvenient!
