Step-by-Step Guide for Wiring a Four-Wire Electrical Outlet

Once you have all the necessary tools and components, you can start on the wiring procedure. Here are the steps to follow:

Before anything else, inspect the wires to ensure they are in good condition. If any of the wires are frayed or the insulation is compromised, it is necessary to replace the affected wires.

Strip off about 3/4" of the insulation from the end of each wire.

Attach the hot wire to the top outlet terminal. Make sure to use the correct screw size and secure it tightly.

Connect the neutral wire to the bottom outlet terminal. Use the same screw size as before and tighten it securely.

Connect the grounding wire to the green grounding screw on the side of the outlet.

If the outlet is a GFCI outlet, attach the bonding jumper wire to the metal mounting strap.

Push all of the wires back into the outlet box.

Secure the outlet to the wall with the proper screws.

Finally, test the outlet by plugging in a light or other device to ensure that the outlet is wired properly.
