Grounding an Old Receptacle

Step 1

If you have an old system with ungrounded receptacles and want to ground one receptacle, shut off power to the circuit, test for power, and pull out the receptacle. Pry out a knockout slug and then twist it back and forth to remove it.

Step 2

Make a pathway for a ground wire. Use one or two fish tapes to run a 12-gauge green-insulated wire from the box to the service panel or to a cold-water pipe.

Step 3

Connect the wire to the ground screw of the receptacle. Connect the other end to a cold-water pipe (not a hot-water pipe, which does not run to ground) with a special grounding clamp.
