30amp, 220V wiring question

barnesrich · 2005-11-26T19:48:32+00:00

Hi All.I have a 30 Amp, 220 volt recepticle to power a shop heater (whichlists these requirments). Ive purchased 10-3 wire for this (though imthinking 10-2 would be sufficient as well).The 30 recepticle I bought has 3 poles on it to hook up the wire (2hot, and one green - neutral).When I wire to my 30 amp breaker, I have 2 hots coming out of thebreaker which would go to the 2 hots on the recipticle.I'll run the ground from the breaker box to the green ground on therecipeticale.What Im confused about:With 110 15 amp I run one hot from the breaker, one neutral (white) andone ground (copper).But where does the white go when im hooking up the 220? Theres nothingfor it on the recepticle, so I guess it isnt used?Any help or explanations would be appreciated!Thanks!

Do something useful. Tell us how YOU would wire it.

I sure hope you have liability insurance there in NY, since you dont have a licence, or a clue.

Wise or otherwise (I wouldn't do it if for any other reason than future wiring confusion) all Stormin suggested was to have two grounds instead of one ground with a extra wire dangling free.......what conceivable danger lurks with such a suggestion? Rod
