Clear wire sheathing


I am trying to install a pool table light. All of the wires coming from the light (3 bulbs, 3 sets of wires) have a clear wrapping with no marking at all on it. Both wires are copper inside. I have no way to distinguish between a + or - wire.

How do I connect this ?? What will happen if it is hooked up backwards
?? Pop a breaker ?? Blow the bulbs ??

Any help would be great

Thanks,

Kevin

Do you have a continuity tester?"What will happen if it is hooked up backwards " The light will work if hooked up backwards the only thing is the socket will be powered backwards the tab in the center needs to be the hot and the screw-in part the neutral if you have a continuity tester test the center tab with one of the wires when you have continuity that is your hot.

I dont think I have a continuity tester......what I have is a small lighted tool with a red and black wire with prongs that I can stick to a an outlet or wires and tell if there is power to them (light turns on).....

Will this work ??

I don't think that will work unless it shows you that the curcuit is reversed.The other way is to hook the hot up and take a short run of wire hook it to the neutral wire put that on one lead of the tester and check the center tab and see if that is hot but you will have to be VERY CAREFULL because it has power . A continuity testers are cheap prob get one at your home store for under $10.00 this would be the best way to do this unless you are comfortable working with power on.

Look closer at the wires you have described. Feel each one along it's length to see if there are any sort of raised "ribs" that run along the entire length of one wire. Some wire manufacturers put these on colored and clear wire to identify the "neutral" wire. Errr, I think I'm right-I'll get corrected if my memory is failing on the correct I.D. of that marked wire. Thanks, David

You are correct, Thurman. The neutral conductor is always marked on "zip" cords, etc. A ridge on one edge identifies the neutral in many cases.

For some reason I can never remember this. Always have to look it up.
