220 volt with 4 wires wiringReport
Please briefly explain why you feel this question should be reported .
My electrician wired my 220 outlet with 4 wires – white, black, red & ground. I have a 3 wire 220 volt 20 amp plug/outlet for a car lift. Which wires will I use and where on the plug? (The machine/plug wires are green, red, black). Thanks!
