Will, If you already have a 220 volt, 20 amp circuit it should have a
6-20R receptacle. The 30 amp plugs are bigger which judging by the
prongs of the plug in your fingers is what you have.

Thanks, John. I'm thinking that the plug is the larger, 30-amp 6-30 as
well. I don't have the recepticle installed yet, just the existing
wire and outlet box. Looks l ike I need to upgrade to 10-gauge wire.

With appreciatiion,
Will
