3 Things to Know About RV Extension Cords

Use only a 30-amp or 50-amp RV extension cord Standard household extension cords are too thin for RVs. They cause voltage drop and risk melting the plug or starting a fire.

Match the cord to your RV’s plug type Most travel trailers use a 30-amp cord with a TT-30P plug (three prongs, round). Larger motorhomes and fifth wheels use a 50-amp cord with a NEMA 14-50P plug (four prongs, like a dryer plug).

Never use a 15- or 20-amp extension cord The wire gauge is too thin for RV power demands. Only 30-amp or 50-amp cords are safe and reliable.
