Any folks know 220 wiring ?

Go to Home depot or lowes., wherever you can get electrical stuff and get a 50amp 240VAC plug and recepticle. They are large, probably more than you will need for the compressor but better too much than not enough. Then you can wire it in the same circuit as your wife's clothes drier... If you are going to use it with your generator you need to know the pin out of the plug. 220VAC has 2 hots and a neutral (common) plus a ground is required in most locales. Use a volt meter with your generator running to see where your voltages are. Between either hot and a neutral you will get 115VAC. Between 2 hots you will get 240VAC. Once you have those figured out, you need to determine which is neutral and which is ground since you will get the 115VAC on either one. Turn off the generator and make sure the breaker for that recepticle is off. Change the multimeter to ohms and go between each pin and a ground on the generator frame. You will only get a readin from the ground since the breaker interupts all 3 of the other wires.
