RV Shore Power Cords & Adapters

The cord between the pedestal and your rig does more work than it looks — carrying your whole electrical load, outdoors, in the weather, plugged and unplugged dozens of times a season. This category covers shore cords in 30- and 50-amp, the dogbone adapters that let you connect when the pedestal doesn't match your plug, generator adapters, locking connectors, and the circuit testers worth using before you trust an unfamiliar post.

Choosing shore cords and adapters

Two numbers decide almost everything here: your rig's service (30-amp or 50-amp) and the pedestal you're plugging into. A 30-amp RV uses a TT-30 plug on a single 120-volt circuit, while a 50-amp RV uses a larger 14-50 plug that's actually two 120-volt legs. Get those straight and the rest is picking the right adapter for the gap.

  • Cord amperage and gauge. Match the cord to your service. A heavier gauge runs cooler and drops less voltage over a long pull, which matters when the pedestal sits far from the site.
  • Dogbone adapters. These bridge mismatches — a 30-amp rig to a 50-amp post, or down to a 15-amp household outlet at home. An adapter changes the connector, not the available power: on a 15-amp outlet a 30-amp rig still only has 15 amps, so ease off the air conditioner.
  • Locking and grip connectors. Twist-lock and grip-handle ends stay put in wind and pull apart without a fight — easier on the plug and on your hands in the cold.
  • Generator adapters. If you run a generator, an L5-30 or duplex-15 adapter matches its outlets to your RV cord.

Before you trust an unfamiliar pedestal, a plug-in circuit tester flags an open ground or reversed polarity in seconds. For the damage a bad post can do beyond that — low voltage and surges — pair the cord with a surge protector or EMS, and protect the panel itself with the right fuses and breakers.
