How to Wire a 220 Volt 3 Wire Dryer Outlet | Hunker

However, the neutral wire is needed if a 220-volt appliance has features that run on 110-volt power, such as a clock or a light. In the past, the neutral path was provided by the ground wire, so the receptacle needed only three wires: two hot and one that combined neutral and ground.

Work on 1 wire at a time or else you won’t remove the insulation as well. Grip the last 1 ⁄ 2 inch (1.3 cm) of the wire in the jaws of the wire stripper and squeeze the handles together. Pull the wire stripper toward the end of the wire to cut off the insulation. Repeat the process for the other 3 wires that were inside the cable.

A 240 volts hookup is usually provided through a two-wire cable such as 12/2, 10/2, or 8/2 or three-wire cable such as 12/3, 10/3, or 8/3, the last digit being the number of wires in the cable excluding the ground wire. In 12/2, 10/2, and 8/2 cables, both wires are hot and carrying 240 volts between them with the white neutral line absent.

A 220-volt outlet is the same as a 230-, 240- or 250-volt outlet. It has two brass terminals for the hot wires, which connect to a pair of coupled circuit breakers. It also has a green terminal for the ground wire. Most 220v receptacles also have a chrome terminal for a white neutral wire.

The wires, or conductors, in those circuits are classified based on wiring type, size, and color, and it is the color of the wire’s insulation which designates the function of the wire. Understanding the information those colors convey helps you work with greater safety and ease when troubleshooting an electrical problem or making repairs or improvements to your electrical system.

The phase types are known as Y or delta. With a Y you have a center that serves as a "return" to carry any "out of balance" condition. It is normally used for high voltage power lines (you will see 3 heavy cables and a light cable). With Delta you will only see 3 wires. 3 phase is rarely, if ever, used in a house. – eddyq May 30 '17 at 13:35
