How to Rewire a Floor Lamp

June 25, 2010

Today I’m going to provide step-by-step instructions with pictures on how to rewire a floor lamp. The lamp cord was damaged and needed to be replaced. In my opinion, this is the best method for repairing a bad or damaged lamp cord. Another alternative would be to use butt splices and heat shrink tubing. However, this looks tacky and very unprofessional.

Before we get started, be sure the lamp is unplugged, remove the lamp shade and light bulb.

As you can see in the image, the lamp cord was damaged. My step son’s puppy chewed the cord. So it needs to be replaced.

You are going to need some lamp cord and a plug for materials to complete this task. These items cost me a little under $6.00 at Lowes.

Step 8. If you look in the hole with the wire, you will notice a piece of spring steel at an approximate 45 degree angle pinching the wire. Simply push down on the spring steel while pulling the wire out.

Step 17. Create a “U” shape with the bare wire. Bend the bare wire approximately 1/2 of an inch away from the insulation. Hook the 2 wires together and wrap the 1 inch tails back on each wire so that it looks like the picture.

Step 18. Use electrical tape to tape up the splice.

Step 24. Connect the neutral wire to the neutral terminal on the lamp socket. The neutral terminal on the lamp socket is marked. The neutral wire in the lamp cord is identified by either writing on the wire or ribs on the wire.

Step 31. Pinch the two prongs together and pull to remove the center portion of the plug assembly.

Step 32. You need the 2 pieces separated so that you can connect the plug to the lamp cord.

Step 33. Insert the lamp cord through the brown outer portion of the plug and into the center portion of the plug. You need to pay close attention to the direction that the lamp cord is placed into the plug. The wider prong is the neutral. The wire needs to be placed into the plug to allow the neutral prong to connect with the neutral wire.

Step 34. Pull the wire back through the brown outer portion allowing the center portion to properly seat and connect to the lamp cord.

Finally, install the light bulb (I recommend CFL or LED), lamp shade, plug in, turn on and test.

    I want to rewire a pool table lamp (large, decorative, hanging) with led lights as economically as possible. Which set up would you recommend (including lumen size). I see screw in “bulbs” advertised but don’t know if they need to be wired with a transformer? Thanks for your advice. Bill
