ECN Forum Forums Technical Discussion Electrical Theory and Applications 220 v

hello again people, I have a question about 220v wiring.

The way I understand it is that between the red and white wires there is 110 volts, and between the black and white wires there is 110 volts, between the red and black wires there is 220 volts.
so technically there is two 110 volt circuits rolled into one and the white wire is only needed for single phase (or 110 volts).

correct me if I'm wrong.
thanx for all the help.

oh, and everyone have a very very merry christmas, from canada.

That is more or less it.

Call it 240/120 though.

oooo I'm gooood, thanks again

I smell a Christmas Tragedy about to happen.

hahahahaha, aaw no don't worry I'm sure those lights can handle the extra juice.

Just kidding

the confusing part is that no matter if it is 110 or 220 volts, it is still single phase.

Just think of it this way:
Phases have to do with PAIRS of hot wires not the number of single wires.

Try to remember not to call every ungrounded/hot/line conductor a "phase" and single phase might make more sense.
