How Do You Wire A 30 Amp 220 Volt Plug?
Trying to wire a modern four-prong 220-volt plug can leave the average homeowner with the strong impulse to call an electrician. Regular 110-volt current is dangerous. 220-volt can be doubly so. One hot and one neutral wire carry 110-volt household current. A ground wire is used to shunt excess voltage away from the circuit in case of a short. The difference in 110- and 220-volt household current is the addition of another hot wire. As long as these wires are correctly wired in the service panel, you can wire your plug safely. Remove 4 inches of the electrical cable’s outer insulating jacket with a utility knife. Do not cut the insulation on the conducting wires. Remove ½-inch of insulation from each of the conducting wires with a wire stripper. Separate the face of the plug from the insulating cover. 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. Attach the conductors to the p
