How to Replace a 120-Volt Electrical Wall Outlet

Attaching a new receptacle to electrical box

Attaching new receptacle to electrical box.

Step 7: Attach Receptacle to Box

Gently push the wires and receptacle into the box – don’t force it. If the receptacle won’t fit, carefully rearrange the wires until you can tuck them all safely in the box.

Which way to face the ground plug on a receptacle?

Whether to install a grounded outlet with the ground plug facing up (as shown in the photo above) or down is a matter of debate among electricians. Some feel that installing the ground plug up is safer (since the hot prongs on a plug will not be exposed if it pulls partly out of the receptacle) while others think down provides the most protection (since the plug will still be grounded if it pulls loose). Both ways are considered acceptable under building codes.

Once the new receptacle is in place, attach it to the electrical box using the two screws so the metal “ears” next to the screws on the top and bottom are flush with the wall.

    Hi, Casey,
    It could be a breaker problem, it could be another outlet in the series, it could be a bad GFCI. This one is better left for a pro that can troubleshoot and pinpoint exactly where the problem is.
    Good luck!

    I have a gfi outlet in my kitchen that stopped working and would not reset. It did not trip a circuit breaker. I replaced the outlet and still no power. None of the others in the same room are broken. Could the problem be further back in the wall?

    How do I figure out which circuit breaker turns off which outlets and then how do I double-check to be sure its off?

    Good safety tip! Always check a switch or outlet to be sure it’s off before working on it.

    I have two ceiling fans (bedroom & living room) which are controlled by wall touch switches. One or both will go during severe storms. I have questioned various Home Depot workers who had no idea what could be causing these occurrences. I don’t want to call an electrician to come over for something I could possibly do myself. I have installed dimmer switches, installed thermostats, toilet repairs, under the sink repairs, faucet repairs… I think I can tackle this one. I just need to know whether if I disconnect it at the wall switch, will it function manually directly from the fan?

    I thank you.
