How to Uninstall Garbage Disposal Electrical Wire

Turn off the power to the garbage disposal's circuit. This is done at the main circuit breaker box. There should be notations next to the breakers or some other indicators inside the panel to tell you which breakers control which circuits. After you flip off the breaker for the garbage disposal, try to run the garbage disposal. If it doesn't come on, you've turned off the correct breaker.

Find and open the access panel on the side of the garbage disposal. Look for the electrical wire snaking into the side of the disposal to locate the access panel. Loosen the screws that hold the panel in place.

Remove any wire nuts connecting the house circuit to the wires in the disposal by twisting the wire nuts on the end.

Disconnect the white wires from the house circuit from the white wires on the disposal by untwisting the connectors. Do the same for the black wires from the disposal and the house circuit. If you cannot disconnect the wires, you can cut off the ends with a pair of wire cutters.

Loosen the terminal screw on the disposal where the green or bare copper wire is connected. Pull the green or copper wire out of the electrical panel. This wire could be connected to another green wire instead of to a terminal screw, depending on your garbage-disposal model.

Cap off the wires from the house electrical circuit with wire nuts. Secure the nuts with electrical tape. Push the wires safely out of the way, such as into a junction box or into a wall cavity.
