An intact plug has straight prongs, a solid casing, and a cardboard insulating faceplate or disc (unless the entire plug is solid plastic). If the prongs are bent, the casing cracked, or the faceplate missing, replace the plug.
Plugs come in a variety of styles including …
➤ Flat-cord plugs.
➤ Quick-connect plugs.
➤ Polarized plugs.
➤ Round-cord plugs.
The easiest plug to install is a quick-connect plug. The prongs of the quick-connect plug can be removed from the casing by squeezing them together. By spreading them, the lamp cord can be inserted. To attach a quick-connect plug, squeeze the prongs together and slide them back into the casing. You don’t have to do any work on the wire; just follow the instructions on the package. Be sure the plug is rated for the load to which you’re attaching it. (You won’t get away with a quick plug on a heavy-duty portable appliance, for example.)
To replace a flat-cord plug, disassemble the casing on the new plug, pull apart the two halves of the lamp cord to the length of two inches or so, strip the insulation off the ends of each half, wrap the wires clockwise around the screw terminals, and reassemble the casing. The quick-connect plug is the easier of these two to install, but it’s not the best choice for a lamp that’s unplugged often.
