about Christmas Lights
Hi, I wanted to know what that third wire is in a christmas light string? At the plug and other end there are 2 wires coming out of them. I'm assuming they're the hot and neutral wires. But between the first and last LED lights there's a third wire connecting all of the lights. I was wondering what that's for? Is that to make the lights a parallel circuit? I thought all christmas lights were series?
And I wanted to know, if I can connect two strings of LED lights together by snipping off the plug ends and wire nutting the hot to hot and neutral to neutral wires together? I know that there's a fuse in the male plug that I'll lose if I do this. Is there anything else I should know about doing this?
