Fixing a broken electrical cord can mean the difference between saving an electrical device or throwing it away and buying a new one. Splicing the electrical cord back together only takes a few minutes using wire strippers and electrician's tape. The main concern is making sure the correct wires are spliced together and properly re-insulated with tape to prevent a shock hazard. Tying the broken ends in an overhand loop adds strength to the repair and will prevent the ends from pulling apart. Once repaired, the cord should be almost as strong as it was when it was new.
Cut away the damaged part of the cord as close to the broken area as possible, leaving two pieces of electrical cord -- one running to the appliance and the other terminating with the plug.
Use wire cutters to strip away 1.2 cm (1/2 inch) of insulation from the two wires on each piece of cord.
Hold the two cut ends together, make a short loop of the pieces, then run the two ends through the loop and pull tight.
Twist the wire strands to prevent unravelling.
Attach the wires from the white wire to the wires from the matching white wire of the second piece of electrical cord and twist together.
Wrap a piece of electrician's tape around the pieces of wire twisted together.
Attach the black wires from both pieces of the electrical cord and twist them together.
Wrap electrician's tape around the black wires.
Straighten the two ends of repaired cord as much as possible and wrap with an amount of electrician's tape at least equal to the thickness of insulation that was pulled off with the wire cutters.
