- 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 - Size of circuit breakers for 220v circuit - Home . . .
I'm considering a piece of shop equipment with a motor that can be wired as 110-volt (20-amp) or 220-volt (10-amp) I'm leaning towards 220v despite the additional cost of installing the electrical outlet The equipment vendor says the minimum circuit should be 15-amp
- electrical - Wiring for 1 phase 220 volt bandsaw - Home Improvement . . .
Splitting DC supplies like that with "taps" is a recurring theme in Edison and GE designs of that age Edison's goal was to reduce voltage drop - 220V distribution has 1 4 the losses of 110V But DC switches need elaborate arc suppression so 110 was better for lighting than 220 220 was better for motors

- Can I extend a 240 V line? - Home Improvement Stack Exchange
I have a 240 V line in my kitchen for an oven We are remodeling the kitchen and moving the oven and, thus, need to move the 240 V outlet Can I extend the line by joining cables in a junction box
- What is the right wire size for a 30A 220 Circuit over 40 ft?
"30A" as a size, 220 colloquially when that voltage is actually fairly rare, Imperial units, casual use of AWG, casual use of 2 3 designation -- each individually is a flag for North America or Philippines All together, sure thing Euro rest of world talk differently If he had said "to the hob" I'd have stopped dead in tracks
- How to connect a 220v gfci that has no neutral coming from the load
On a boat dock with a220v boat lift I have pulled 2 hots and a ground as that’s all that is required to operate the lift motor My Bldg dept is requiring a GFCI 220 breaker I assume the pigtail wi
