Lighting Week! Rewiring 101

By Danikaherrick @danikaherrick
Many of you know that I have a little problem with collecting (hoarding) old light fixtures. I will see a cool lamp or swag pendant at a yard sale and think "That would look great painted gold" or "I just need to change the shade" and it gets added to my pile.  
Paint and new shades are the easy part, but almost all of these fixtures require new electrical wiring.
In honor of this obsession of mine I decided to make this week dedicated to lighting.
Lighting Week! Rewiring 101 Let's kick it off with a talk about rewiring.
There are many levels here, but I say we take baby steps and start with a common lamp.
It can seem very daunting and scary.  I remember the first time I rewired a lamp- I flinched as I turned the switch on fearing I did it wrong and was going to electrocute myself.
Obviously that didn't happen, and I slowly gained more confidence.
Once you understand the basics you will start seeing the possibilities
 every time you pass an old discarded light fixture.
 Now I like to pretty much rewire ALL old lamps for safety's sake.
Call me a Nervous Nellie, but you don't know why someone gave up
 that lamp to begin with.
You don't  know what lurks inside or how sound the connections are.
I just sleep better knowing the wiring is new and correct.
For this post I happened to have a newer lamp that was giving me trouble.
It would only turn on occasionally,
and I usually had to jiggle the switch to make that happen.
I figured there might be a loose wire (dangerous) so I decided to investigate.
Before we begin: ALWAYS MAKE SURE YOUR LAMP IS UNPLUGGED!
 I started by pulling off the cardboard/metal sleeve that covers the socket.  Lighting Week! Rewiring 101 Usually all it takes is pinching the lower part near the switch and pulling upwards,  but mine wasn't cooperating.  I had to use a screwdriver to pry it off, damaging the base. But I did find the problem! Lighting Week! Rewiring 101 Since this post is about "how to rewire" I was fine with the damage since I was planning on giving it all new guts (new socket and cord).   I headed over to my local True Value to gather my supplies... Lighting Week! Rewiring 101 I went straight to the electrical department where they have everything you could ever want  and amazing customer service to boot. I could seriously sing their praises all day.   If you get overwhelmed there is always someone experienced to help you figure out exactly what you need.  I highly recommend bringing your light fixture with you if are at all confused. Lighting Week! Rewiring 101   My local store will even rewire fixtures for you!  I have had them do a couple tricky chandeliers and lamps for me in the past, and they even replaced the cord on my vacuum.  
 I brought my old socket with me and I found a match... Lighting Week! Rewiring 101 and I bought an 8' lamp cord set...
Lighting Week! Rewiring 101  I am a big fan of kits since they save time and a few steps, but you can also buy the cord by the foot and attach a separate polarized plug if you wanted a  longer/shorter cord in a different color.
Once you have your replacement parts you are ready to start.
You will need access to the base where the cord is fed into your lamp.   Mine had a protective/decorative cover that I had to cut into: Lighting Week! Rewiring 101 Next, using wire cutters I cut off the old cord/plug near the base.  Lighting Week! Rewiring 101  If you are using a plug kit like I am you will have to feed the new cord in through the bottom. If you are using cord by the foot with a separate plug  you have the option of feeding it through the top or bottom. In many cases you can simply tape the new cord to where you just cut the old cord...  Lighting Week! Rewiring 101  and pull the cord up from the bottom to the top. Lighting Week! Rewiring 101  My lamp was proving to be quite difficult on many fronts.  Right before the wire got to the top it got stuck and broke off from the tape.  I needed to remove the top neck/nipple to get it out. Lighting Week! Rewiring 101  Once I did... Lighting Week! Rewiring 101 it popped right through.  Lighting Week! Rewiring 101  I threaded the cord through the nipple and re-screwed that back into the lamp base. Lighting Week! Rewiring 101  Now it was time to wire the socket.   First loosen the side screw on the base of the socket... Lighting Week! Rewiring 101 and attach it to the nipple by twisting it on and then tightening the side screw.  Lighting Week! Rewiring 101  Prepare your wire by snipping into the top to split it. Lighting Week! Rewiring 101 You want to pull it apart about 4-6 inches and separate the the two wires.  Lighting Week! Rewiring 101  Using wire strippers, strip off about an inch of the plastic protecting the wires.  To do so just center the wire in the proper size grove, clamp down and pull along the wire. Lighting Week! Rewiring 101  You should be left with abundant clean wire and no plastic. If a lot of wire got cut off with the plastic, go up a size in the grooves. If you still have plastic coating over the wire, go down a size. Lighting Week! Rewiring 101  Now you will need to tie an underwriter's knot with the wire. The plug kit gives you an illustration of it on the backside, but basically you loop both wires and then have the opposite wire go through the other.  This prevents the wires from getting pulled out of the socket if someone pulls the cord really hard. Lighting Week! Rewiring 101 Before connecting the wires to the socket I like to mark the live wire with a Sharpie.  Since they both look the same it can get confusing.  This helps to eliminate the fear that you wired it wrong. If you feel along the edge of you cord you will notice  one side has a smooth edge and the other is ribbed.   Smooth is your live wire side,  ribbed is the neutral side. Lighting Week! Rewiring 101 Slide the sleeve off your socket... Lighting Week! Rewiring 101  Take your live wire and twist it tightly together and then bend it like a candy cane. Lighting Week! Rewiring 101 THE LIVE WIRE GOES TO THE COPPER SCREW,  THE NEUTRAL WIRE GOES TO THE SILVER SCREW.  Lighting Week! Rewiring 101  Loosen each screw and hook the wires behind. Now tighten the screw until the wire is firmly attached.  You want to squish it tight.  Lighting Week! Rewiring 101 Slide the sleeve back over the socket  and press it firmly into the base until it is locked in place. Lighting Week! Rewiring 101  Give a gentle tug at the base if you have too much wire up on top. Lighting Week! Rewiring 101 Now for the true test. You can now add a bulb,  plug your lamp in and test it out. Lighting Week! Rewiring 101  Success!   I finally have the pair working safely together! Lighting Week! Rewiring 101
Stay tuned.
I have a 'Rewire 102' for hanging fixtures and tons of lighting inspiration coming up!
