Home Repair Tips – Appliance Wire

Filed Under: Do it yourself, Electrical, Home repair    by: ITC

Appliance wire is a good conductor, but it pulls apart easily. The wires inside most electrical cords are in strands. They are not solid like permanent wiring in the walls. The insulation around the wires is strong and helps hold the strands together. The wire usually breaks before the insulation does and you will not be able to see where it is broken. When the wire breaks, the lamp may go out entirely. If you move the cord or hold it a certain way, the lamp may go on again.

To check a lamp cord, plug it in and use a circuit tester to test the ends of the wire closest to the lamp. If the tester lights, the circuit is complete and there is nothing wrong with the cord. Most likely, the lamp socket is defective. If the circuit tester does not light up, flex the cord and see if this makes the circuit tester flicker. Be very careful while the cord is plugged in.

If the cord is bad, remove it. A replacement cord has a molded plug at one end and bare wires at the other. Be sure to replace the cord with one exactly the same. Heating devices especially require a special type of cord. Attach the new cord exactly as the old cord was attached.

If the cord is good, but the lamp still doesn’t light, the problem is usually the lamp socket, which contains the switch. The lamp socket has four basic parts:

• Cap

• Socket

• Cardboard liner

• Outer shell

When you buy a new socket, be sure to get the same kind. Although they may look alike, sockets come in different sizes and types.

Before working on the lamp socket, unplug the lamp and remove the bulb. On the outer shell there is a spot marked PRESS. By pressing and wiggling it, you can remove the outer shell and the cardboard liner. Unless the cap is damaged it probably does not need to be replaced. In the cap, the wires are tied in an underwriters knot. Examine the wires. If the insulation is brittle, cut back the wires or replace them. Tie an underwriters knot. Then attach the ends of the wires to the new socket just as they were on the old socket. Set the socket back in the cap. Replace the cardboard liner. Plug in the lamp and test it.

So they will be flexible, most lamp d appliance cords are made of hair-like strands metal in an insulated shell.

A wire may break or burn through _nder the insulation. Broken wire can cause sparking that will burn the insulation.
