I have a 30 Amp, 220 volt recepticle to power a shop heater (which
lists these requirments). Ive purchased 10-3 wire for this (though im
thinking 10-2 would be sufficient as well).
The 30 recepticle I bought has 3 poles on it to hook up the wire (2
hot, and one green - neutral).
When I wire to my 30 amp breaker, I have 2 hots coming out of the
breaker which would go to the 2 hots on the recipticle.
I'll run the ground from the breaker box to the green ground on the
What Im confused about:
With 110 15 amp I run one hot from the breaker, one neutral (white) and
one ground (copper).
But where does the white go when im hooking up the 220? Theres nothing
for it on the recepticle, so I guess it isnt used?
Any help or explanations would be appreciated!
