Learn basic, code-compliant wiring techniques for outlets and switches.

Check that the current has been disabled using amulti-meter or similardevice before proceeding.

Inform yourself aboutelectrical safetybefore beginning your rewiring outlet task.

Another way to wire an outlet is to use the stab-in connectors on the back of the outlet.

Strip the Wire

Strip about 3/4-inch of insulation from each circuit wire using wire strippers.

(The ground wire may not be insulated.)

Materials and tools to wire electrical outlets and switches

Attach the Wire to the Screw

Fit the hook of each wire over the appropriate screw terminal.

The stripped copper end of the wire should be exactly the depth of the hole.

If the copper end is too long, it may contact another wire and short out the outlet.

Because the hook is wrapped clockwise around the screw, tightening the screw closes the hook even more.

The screw should be very tight, holding the wire firmly below the screw head.

Outlets must be grounded.

A GFCI outlet can provide GFCI protection for all downstream devices or just for itself.

How to Wire a Three-Way Switch

Three-way switchescontrol a light fixture or outlet from two different locations.

These switches have two traveler wires and a single common wire.

Usually, the gold terminals on an outlet indicate hot wire connections.

Because this is not always reliable, it is safest to test the outlet with a voltage detector.

Yes, it is possible to wire an outlet backward.

Polarity keeps the electricity flowing in the proper direction.

Connect the white neutral wire to one of the neutral silver-colored terminals.
