Wire a New Electrical Outlet Off a Switch

Replacing an electrical outlet that is on a switch is actually easier than you may think. Follow these steps and you will have your new outlet installed in no time.

Why Replace It?

A faulty electrical outlet can cause a short or blow a circuit, leading to loss of electricity as well as possible fire and electrical shocks.  If you have a faulty outlet, replace it immediately.

Switch

If the outlet you need to replace is on a switch, chances are you will only have to replace one switch or outlet from the hookup. Note that the switch is always on the hot side (black wire) of the circuit. Always remove the fuse or turn it off at the breaker before removing the switch plate.

Combination Switch/Outlets

Many people like the convenience of having a switch and outlet in the same place, which is common in garages and bathrooms. For this type of replacement have jumpers on hand since each unit will have a separate connection.

Remove the Old Outlet

Always make sure the power supply has been shut off before attempting any electrical work.
Remove the outlet plate and the two screws that hold the unit in place. Pull the outlet out of the liner and remove the wires.

Terminal Positions

If your outlet is on a switch, you’ll need to take a look at the positions of the terminals. While the position may vary from brand to brand, the concept is always the same. Just make sure that the new outlet has the same placement as the old one, especially with the screw terminals.

Place New Outlet

Now that you have the old outlet, you can start wiring the new outlet receptacle. Follow local code and guidelines to ensure each switch or outlet is grounded and wired correctly.
Then place the receptacle back in the box, and replace the faceplate.

Check Other Circuits

If the outlet is on a switch, take the time to test the other switches on the same line and replace faulty ones.

Troubleshooting

If you live in an older home, you may encounter flash wiring, a more complicated and potentially dangerous situation to work around. If you take off the plate and discover burn or char marks, or if the wiring is old and frayed, you may want to leave the job up to a licensed electrician. It’s generally wiser to have a professional tackle older wiring.
