I'm sure we've all been there - noticing that one loose, disconnected wire behind an outlet that you have no idea what to do with. It's been back there for who knows how long, and you can't just leave it - it needs to be dealt with. But electrical work can be daunting, and this weird wire is just confusing. Well, it's time to finally fix this issue once and for all.
Identifying the Wire
The first step is to identify what type of wire this is and what it was likely originally connected to. Here are a few possibilities:
Ground Wire
- The ground wire is an exposed copper wire that connects outlets and fixtures to the ground.
- It helps prevent shocks and protects from faults.
- A disconnected ground can be dangerous, so this would need to be reconnected.
Neutral Wire
- The neutral wire is typically white or light gray.
- It carries electricity back to the breaker panel.
- A loose neutral could cause appliance issues or lights to flicker.
Hot Wire
- The hot wire brings power from the breaker to the outlet.
- It's usually black or red.
- A disconnected hot wire means the outlet or switch won't work.
Capped Extra Wire
- Sometimes extra wires are stuffed into the box, capped off and left unused.
-Determine if this wire is live or if it's orphaned before removing.
So take a close look and see if you can identify what type of wire this is in your outlet.
Turn Off the Power
Before doing any electrical work, safety should be the top priority. Make sure the power is shut off at the breaker before touching any wires.
- Go to your electrical panel and flip the breaker switch that controls the problem outlet to the off position.
-
To be safe, I like to turn off the main breaker if I'm unsure which one it is.
-
Test the outlet with a voltage tester to confirm power is off.
-
Put a piece of tape over the breaker switch as a visual indicator the power is off.
Working on an outlet that is live can result in dangerous shocks. Take the time to power down the circuit you're working on.
Remove the Outlet Cover
With the electricity safely powered down, now you can dig in to fix that wire.
-
Unscrew and remove the outlet cover plate so the inside of the electrical box is accessible.
-
You may need a flat head or Phillips screwdriver depending on the type of outlet cover screws.
-
Carefully remove it and set it aside in a safe place.
Inspect the Wire
Take a close look at the disconnected wire and try to determine:
-
What color it is - this can indicate if it's a hot, neutral or ground.
-
Where it runs - follow where it's routed to get clues about its original connection.
-
If it's live - use a non-contact voltage tester to check if power is running through.
-
If it's capped off - see if the wire is cleanly cut away from a connection and protected with a wire nut.
Thorough inspection will help you identify the wire and determine the appropriate remedy.
Reconnect It Properly
Once you've determined what type of wire it is, it's time to make the proper connections:
-
Hot wires get reconnected to the hot terminal on the outlet or to another hot wire.
-
The neutral wire gets connected to the neutral terminal or another neutral running to the panel.
-
Ground wires get screwed into the green ground screw terminal on the outlet.
-
Capped wires can usually be neatly tucked into the electrical box if they're not needed.
Make sure hot and neutral wires have enough exposed copper to make solid contact with their terminals.
Secure the Connections
It's critical that all wires are securely fastened to prevent loose connections that can spark fires or shocks:
-
For outlets, wrap the exposed wire clockwise around the hot or neutral terminal screws and tighten firmly.
-
For joining two wires, twist matching colors together clockwise and secure with a plastic wire nut.
-
Tug test each wire to ensure a tight connection.
-
No exposed copper should be showing once connections are made.
Don't forget to reconnect the ground wire to ensure outlet grounding protection is restored.
Restore Power and Test
You're almost finished - it's now safe to turn the power back on and make sure the outlet is working properly:
-
Turn the correct breaker back on at your electrical panel.
-
The outlet should now be receiving power as normal.
-
Plug in a lamp or other appliance and turn it on to verify proper operation.
-
Also check nearby outlets and lights to make sure they're still functioning.
-
If the outlet isn't working, turn the power back off and check that all wire connections are correct.
That should take care of that nagging loose wire issue behind your outlet. Just be sure to turn the power off first, make solid connections, and test the outlet before buttoning it up. Then you can finally relax knowing that weird wire is fixed, no longer a safety hazard.
