- electrical - Confusion over 220 and 230 volt outlets - Home Improvement . . .
220 wasn't even the original voltage It was 200, or to be more precise 100 100 split phase, and 500V for streetcars It was also DC A bump was made to 105V etc in coordination with light bulb makers Then another bump to 110 220 550, and then, power companies yielded to the inevitable and switched to AC
- electrical - How many amps per leg on a 220V circuit? - Home . . .
220-240v in the U S is 2 legs of a single phase The 2 legs come off the transformer and have a center tap (the neutral) each leg to neutral is 120v or 240 leg to leg If it were part of a multi phase phase system the leg to leg value would not be the same as adding each leg to neutral voltage –
- electrical - How do you do a 220, two lives, one neutral, one ground . . .
But how, if you have the two live lines wires +neutral, how would you make the connection using the rail ones, two breaker? One breaker for line 1,second breaker for line 2, in that how can you distribute that to let's, say a 220 A C, thanks for your answer –

- electrical - Why Do 240V Circuits Not Require Neutral? - Home . . .
All electric circuits require 2 "sides" or "legs" of power regardless of voltage or polarity be it a 12 v DC circuit in a car or a 120 v AC wall outlet or a 220 v dryer outlet 1 hot leg is 120 volts, 2 hot legs is 240 volts across both legs with a 120 volt circuit we only use 1 hot leg, so what is the 2nd leg going to be if not the other side
