How to Wire a Bulb Socket Light Fixture: Detailed Step-by-Step Guide

Prep the Light Socket Wiring

  1. Grab the cord grip and untwist the cap.
  2. You might need to place tape around the end of the cord, so the cord grip and cap can slide over the cord easily. Try spinning the cord grip into the cord if it gets stuck.

Connecting the Cord Grip

  1. Insert one end of the light socket wiring into the top hole of the cord gripʼs cap and then the cord grip. The cord gripʼs threaded end should face the end of the cord once inserted.
  2. Measure 11/4 inches from the tip of the light socket wiring, and wrap an inch of electric tape over the wire. 

Grounding the Wiring

  1. Over the midsection of the tape, strip the PVC housing to expose the 3 conductor wires. We recommend using our Color Cord 3000 striping tool or a stripping tool of your choice. 
  2. Make sure that there are no cuts on the conductor wires exposing the internal stranded copper wire.
  1. Strip one end of each wire to expose about 3/16 inches of stranded copper wire.
  2. Using your fingers, twist the stranded wires together.
  3. Flip the cap upside down & locate the screw of the ground terminal. Loosen the screw about ⅛ inch.
  4. Bend the exposed end of the ground (green) wire to a 90-degree angle.
  5. Insert the ground (green) wire through the top opening of the cap.
  6. Insert the exposed section of the green (ground) wire into the ground terminal opening under the screw.
  7. Make sure the exposed copper light socket wiring is completely inside the hole. Then secure the wire in place with the screw.

Finishing the Wiring

  1. Insert the black and white wire through the top opening of the cap and push the wire inside the cap. 
  2. Flip the terminal upside-down & locate the positive & negative ports. The positive terminal will be the bent brass plate, and the negative the open plate that reveals the silver piece underneath. 
  3. Flip the terminal again and locate the corresponding positive and negative terminals, which will be directly above the + & - ports. 
  4. Align the cap with the terminal, so the black wire is aligned with the positive terminal, and the white wire with the negative. 
  5. Insert the black-stranded copper wire into one of the two round positive terminal holes, and the white-stranded copper wire into one of the circular negative terminal holes.
  6. Make sure the stranded light socket wiring is all the way in, and that each wire is locked in place. If done correctly, you won't be able to pull the wire out of the terminal.

Locking the Socket

  1. Align the wings of the cap and side pockets of the terminal. Push them together until the socket locks.
  2. Take caution when sliding the cord grip down the cord towards the socket so as not to snag the cloth covered wiring.
  3. Twist the threaded cord grip into the socket, and then slide the cord gripʼs cap over it and twist it until it covers all the threads. The cord grip might be tight and will take some force to screw it into the threads. Don’t be discouraged!

Light Socket Wiring FAQ

Is this wiring guide only for porcelain sockets?

No! You can use our light socket wiring guide for any socket in our collection, including metal and plastic varieties. While there may be a few differences in the placement of the screws or the cap-locking method, the overarching instructions are the same.

Does it really matter which wire connects to which screw?

Yes, how you wire a bulb socket is critical to ensuring your safety, as well as a working light bulb. You must connect the wire colors to their matching ports. Green is your grounding wire, black connects to the positive terminal, and white connects to the negative terminal.

What happens if you wire a socket wrong?

Incorrect light socket wiring can be incredibly dangerous and may result in short circuits, severe electrical shock hazards, ruined light fixtures, and even electrical fires. Reversing the black and white connection or improperly grounding your light fixture can reverse the polarity of your socket. Some warning signs of improper wiring include:

  • Warm outlet
  • Buzzing sound
  • Breakers keep tripping
  • Fixtures are lit even when off
