I am finally rewiring an old crystal 5 arm chandalier. I have a couple of questions ..One , by 'ribbed' do they mean one single small rib on the wire ? I bought some lamp cord, but I can't tell too easily which one is suppossed to be the neutral and which one is hot..the "rib" seems almost nonexsistant unless I got the wrong stuff.
Two, when I took out the old wires , there was a small, uninsulated wire soldered to the nipple holding the socket on one end, and one of the wires where it exited the arm on the other end...I guess a ground wire . I am using the same sockets. Do I need to do this also ? Thank you in advance
