One of my most-read posts – and the post that really got me taking my blog more seriously- is my tutorial on how to convert a light fixture to a plug-in style lamp, but for some of the applications where a portable-chandelier lamp comes in handy, it can be easier and safer to use a different method than the one described in that article. In this article, we’ll discuss how to safely splice together a chandelier (or any hard-wired electrical device) to an extension cord.
What you’ll need:
– Extension Cord
– Heat Shrink Tubing Sleeves
– Heat Gun or Mini Butane Torch (both work great for epoxy resin projects, as well)
– Wire Strippers (scissors can work in a pinch if you are careful)
Splicing A Light Fixture to an Extension Cord
Light fixtures are, as the name indicates, usually “fixed” in place via permanent mounting. Converting a fixture, instead, to power via an extension cord frees you to be able to create dramatic lighting anywhere.
1. With extension cord unplugged, use sharp scissors to cut off the female end of the extension cord (That’s the end you’d typically plug your vacuum, appliance, etc into- not the end that plugs into a wall outlet)
2. Next, strip off a few inches of the outer covering of the extension cord. You should find within the cord a black wire, a white wire, and a green grounding wire.
3. Remove the colored coating from those inner cords, exposing the copper wires. You’ll need about 1 inch of exposed copper showing.
4. Next, shift your attention to your light fixture. How do the wires appear? Most light fixtures will already have wires exposed and ready, but if they aren’t- or if they are very frayed by previous use, you can cut the wires back a bit and prepare them in the same way you prepared your extension cord.
5. With light fixture wires prepared just like the extension cord, slip a wide Heat Shrink Tubing Sleeves over all three cords and down onto the main cord, and then, also thread a smaller heat shrink tube down each of the 3 individual wires (a total of 4 tubes total).
6. With tubes in place ready to cover the connections to be made, begin joining the corresponding wires together: black to black, white to white, green to green. Firmly twisting the matching exposed copper wires firmly and smoothing excess wire on one side, parallel with the wire.
7. Next, for each wire, slide the Heat Shrink Tubing Sleeve back up the wire until it completely covers the wire’s exposed areas. Use a heat gun (you can also CAREFULLY use the heat of a lighter, mini torch, or candle) to cause the sleeve to contract around the wire. If any part of the wire is still exposed, remove, untwist, and start again with a new tube.
8. Repeat Step 7 for each of the wires, after all three wires have been individually joined and covered with individual heat shrink tubes, slide the final, largest heat shrink tube over the bundle of joined wires and carefully shrink the outer sleeve over the bundle of wires.
9. If you’ve securely covered every exposed wire, with generous overlapping so shifting will not expose wires, you should have a connection safe for use in any dry area.
If you are at all concerned with your final product or confused by any step of the instructions, consult a licensed electrician.
