40 foot extension cords are expensive and heavy. They take up a lot of storage. Just think... EVERY string of lights has to have it's own extension cord. 48 channels needs 48 extension cords.
This year I have decided to make my own custom length extension cords out of lamp cord. SPT2 cord is 10Amp rated for indoor/outdoor use.
I bought spools of green and white SPT2 cord from Action Lighting (
here). I also purchased bags of
male and
female plug ends. These ends are referred to zip or "vampire" plugs. They have "teeth" that the wire is pushed into to make contact with the wire, through the shield.
Here is my process:
Start with the spool of wire
Cut it to length
Split the end
Thread it into the hole. I place the ribbed side of the wire to be in contact with the wide prong/slot.
Push the wire into the "teeth"
Close the cover (yes it takes a bit of pressure)
Finished
Repeat, repeat, repeat until all of your custom extension cords are complete!
