Homeowner wants a 30 amp 125 volt trailer plug out by the driveway to power up the camper while its sittin in the yard.We will have to trench out from the house and mount the outlet on a post next to the camper.Does the 30 amp 125 volt plug require GFCI protection.We plan to run pvc out from the house to a 2-gang bell box with a bubble cover to protect it from rain.
210.8(A) Dwelling Units. All 125-volt, single-phase, 15- and 20-ampere receptacles installed in the locations specified in (1) through (8) shall have ground-fault circuit-interrupter protection for personnel.
Might want to dig a little deeper. I don't have my book handy but I believe all outlets in an RV park have to be GFI. That may carry over to a residence. I know I put a GFI on my personal 50 amp RV outlet without even thinking about it. Considering how bad RVs are wired in general, its cheap protection. See my pictures titled 'Vintage Motorhome' for a typical RV wiring job.
