How to Wire a 30 Amp 220 Volt Plug
- 1). Remove 4 inches of the electrical cable's outer insulating jacket with a utility knife. Do not cut the insulation on the conducting wires.
- 2). Remove ½-inch of insulation from each of the conducting wires with a wire stripper.
- 3). Separate the face of the plug from the insulating cover.
- 4). Slide the wire through the back of the insulating cover. Once the plug has been wired, there will be no way to fit the cover over the plug without rewiring.
- 5). Attach the conductors to the plug's terminals and tighten them with a screwdriver. Attach the bare ground wire to the terminal connected to the rounded prong. Attach the white, neutral conductor to the terminal connected to the "L" shaped prong. Attach the red and black conductors to the terminals connected to the straight flat prongs. It doesn't matter which flat terminal these are attached to, they are both hot wires.
