Repairing a broken wire requires a few tools and supplies and can be completed by most do-it-yourselfers. Be sure that the cord is removed from the electrical outlet before beginning the process. Tripping over a lamp cord or running over the stereo cord with the vacuum both have similar results: darkness and silence. Even if the wire is not severed or separated completely from the plug, a damaged electrical cord poses a health and safety hazard that must be repaired as soon as possible.
Strip about ¾-inch of insulation from the wire. Twist the loose wires between your fingers to bind them together.
Wrap the entire length of the repair with electrical tape, starting about one inch below the repair. Continue to a point one inch past the repair and cut off the tape.
