My house (built in 1955) has four fluorescent lights that shine light through glass blocks in the bar. They are wired together with exposed cloth coated wire behind a brick wet bar in the finished basement. As is shown in the picture, the wires are not protected at all and are not stapled to the wood supports or run through holes drilled in those 2x4s. They are also run from less than 12" from the ground to counter height (one wire runs out of the top of each light and another into the bottom). They just sort of hang there. I know that this is not code (i.e., not safe) and I want to make it safe, especially because I have a young child (I do have a baby gate blocking off the bar, but sometimes it's left open and I am also concerned about adults who go behind the bar) but I'm not sure the best way to proceed. I plan on disconnecting the lights and installing a GFCI outlet where the wire comes out of the wall (which is all knotty pine), but my wife really wants the lights, so I think I'll run new wire off of the load on the GFCI that I will install to feed the lights (either these or new LED ones-- I am very concerned with energy efficiency, but I also have to consider $). It looks as if I could rewire the existing lights, but is it sufficient to just drill holes in the support 2x4s and feed new Romex through the way you would in an unfinished garage or basement or should I use some sort of conduit because of the height of wire? Any advice would be much appreciated. Thanks in advance!
I would think that drilling new holes and running new wires would be sufficient.
If you really want to be safe you could use BX or armored wire. The wires are covered with a metal sheathing.
Another option would be wire mold or plastic conduit fastened onto the supports.
Hope this was helpful
