Hi-

I am installing an isolation transformer and want to isolate the ground
from the shoreside supply. The manual from Charles states that I need
a 2-pole GFCI circuit breaker. I have not found any marine breakers
for 30 amp 120v that are also ground fault. Anyone have any
information on a manufacturer? Or does one use residential vice marine
in this instance?

THANKS for any help.

Bud
