Remove the cord from its power source. Cut the cord fully in half with the pocketknife to reveal a clean cut to the copper strands.

Using the wire strippers, strip the black, white and green insulation to expose three-quarters of an inch to one inch of the copper wire. Twist the bare copper wires together using your fingers in the following order: Attach the two black wires to each other, as well as the white wires. The green wires, if used, must also be attached to each other.

Wrap three inches of electrical tape securely around the black wires. Cover the bare copper to insulate the connection. Perform the same operation on the white and green pairs.

5
Hold all the wires together and insulate the small bundle with the black tape. Attach one end of the tape to the outer insulation of the cord. Begin 1 inch from the exposed black, white and green wires. Cover the insulated wires by wrapping the tape around them in a continuous fashion until you have reached the other end of the outer insulation. This temporary splice will be sufficient for operation in a dry area.
