How to Choose Electrical Fittings and Receptacles
1. Match Amps and Plug Style
Make sure the plug, receptacle, and cord all share the same amp rating and NEMA configuration. A 30A TT-30 RV plug won’t fit a 50A NEMA 14-50 outlet, and twist lock connectors lock in place for generators and shore power.
2. Go Weatherproof Outdoors
Outdoors, use weatherproof boxes, in-use covers, and liquidtight or rigid conduit fittings, and protect receptacles with GFCI where code requires it. The Type filter groups Boxes and Covers, Conduit and Fittings, and Plugs and Receptacles.
3. Finish the System
Pair your fittings with AC panels and breakers and PV wire and connectors, and keep good electrical tape and a few cable glands on hand for the finishing touches.
Electrical Fittings FAQ
A TT-30 is a 30A, 120V outlet used by many travel trailers. A NEMA 14-50 is a 50A, 120/240V outlet used by larger RVs and many EV chargers. Match the outlet to your RV’s power cord.
Code requires GFCI protection in wet and outdoor locations like bathrooms, kitchens, garages, and exterior outlets. A GFCI outlet cuts power in a fraction of a second if it detects current leaking to ground.
Liquidtight flexible conduit protects wiring in wet or outdoor locations where you need some flexibility, like connections to air conditioners, pumps, and inverters. Use liquidtight connectors made for your conduit type.
