I have installed a single pole 30amp outlet in a large barn/shop building so I can plug in my RV camper/trailer when it is parked in there. Does this outlet need to be protected by a GFCI circuit breaker? I would think the circuits inside the RV are enough protection, but not sure.
Thanks, Guy

The 30 amp outlet is dedicated for use by the motor home. It does not need a GFCI.
