KEY DIFFERENCES BETWEEN 30 AND 50 AMPS

  • Plugs on RVs with 30 amp service and 50 amp service differ in design.

    • A 30 amp RV plug has three prongs – a 120 volt hot wire, a neutral wire and a ground wire – and is generally used on RVs with lower load requirements.

    • A 50 amp RV plug has four prongs – two 120 volt hot wires, a neutral wire and a ground wire – that supply two separate 50 amp, 120 volt feeds.

  • A 50 amp service RV provides a maximum 12,000 watts.

  • Even with an adapter, your 30 amp service RV won’t receive more power than the 3,600 watts it can handle.

  • Conversely, if you use an adapter for a 50 amp RV, you’ll be limited to 3,600 watts.
