Question:

Hello, I have 2 receptacles outside my house that I need some information on. Ive attached photos of the receptacles. Both of them are 3 prong twist lock receptacles, and there is a 20A breaker that supplies these plugs. Can you tell me what the NEMA name and voltage of these 2 plugs are? Thank you for your time

Expert Reply:

Thanks for the photos. The plugs are 30 amp twist plugs, but it is obvious the breakers are restricting them to 20 amps. The voltage is 120. You would use an adapter like the Mighty Cord Generator Adapter Plug for RV Power Cord - 3 Prong Twist Lock - 30 Amps A10-G3030AVP to give you the converter for RV power. Alternatively you could use a longer adapter like the Mighty Cord Generator Adapter for RV Power Cord - 30 Amp Female to 30 Amp Twist Lock Male - 12" # A10-G30430VP.

If you want more standard 20 amp plugs you can use the Mighty Cord Generator Adapter Y-Cord - 30 Amp to 20 Amp - 3 Prong Twist Lock to 2 NEMA 5-20 Outlets # A10-G3020Y.
