Can I use Ethernet cables as electrical wiring?
Yes and it is a very good idea for SMALL electrical prodjects. What you need to do is clip the 2 ends of the ethernet cord and throw them away. Then you need to strip the rubber case that is on the outside of the cables. Its about 1 MM thick so be careful. Use like a scissors and make a little shallow cuts around the cord (O and by the way we are stripping the case of the real cords right now). Do this every foot or two and pull the rubber case off. There should be many little cords in there called CAT 5. Take two of those cords out and strip the ends of them and you have two perfectly good cords to work with (you can use the other cords as well of course). Thats pretty much all you have to do. Hope this helps!
