I am doing wiring in my shed on preexisting light fixtures and outlets. the wiring that was disconnect from that carried the electricity to it. What I am trying to do is have all the light fixtures work of an extension cord. I have another extension wire connected to that with the +, - and 0 showing. The fixtures have 3 wires coming out of them what I think to be the power in, power out, and switch. On the fixture on the end I connected my extension cord thing and it work, BUT only that one. The rest of the fixtures did not work, I do see anything wrong. What I thought was that I was connecting to the switch wire so I changed it and it just buzzed with blue light. What is going on?
A typical light fixture has three wires: black, white and green (or uninsulated copper). If there is no green or uninsulated copper wire, there is generally a ground terminal where the ground wire should be attached. The smaller of the two slots in the extension cord (assuming U.S.) is the hot wire and that's where the black wire should ultimately be connected. The white wire nuetral is connected to the other side, the wider of the two slots. The ground is connected to the U shaped terminal below the two slots. There must be a thousand websites with instructions on how to wire a light fixture. Try getting a diagram from one of them.
the rest of your light fixtures maybe wired through a switch. you would have to hook your extension cord to the switch but you also need to connect the common neutrals and grounds to the cord as well.
Oh Abdullah, instead read Alexander Pope's An Essay on Criticism, and read slowly the lines a little learning is a dangerous thing and fools rush in where angels fear to tread, then go find someone a little less hyper and a little less dangerous to help, or else somebody's going to get hurt!
