- 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 –

- What voltage amperage garage circuits should I install for welding . . .
Good home-gamer compressors similarly require 16A at 220 240V, although you might be happy with a 2hp which will run happily on 240V 13A The limiting factor with compressors is startup current - they briefly draw a higher current to get moving, if the voltage sags because the circuit can't deliver enough current you'll likely damage the motor
- Outlet with power wont supply power to anything plugged in
Today we came back from church and our bedroom outlet did not supply power to the tv or cable box Breakers were fine but reset Power tester (stick like unit that sticks into the slot and buzzes)
- 120v vs 240v Mini Split Efficiency - Home Improvement Stack Exchange
Power wise equal btu's and equal seer rating should use the same power Depending on balance of load on half the transformer winding a 120v may produce an efficiency problem with the transformer, but I've never seen a study of the ability or inability of the residential meter to compensate for that
