This project was my first time not doing the DIY thing. I hired someone my boyfriend knew to do the work and he has some beautiful projects in his "portfolio". However, a quick, 2 week reno is now in it's 4th week. The shower he said would be out of commission for 2 days hasn't been working for at least 3 weeks...and this is a one-bathroom condo! I'm lucky to have a wonderful neighbor who lets me come and go in her place (I take my showers next door...it's like being at camp!). The tile work was completed on Monday and the plumber was supposed to come Monday night to install the shower fixtures and install the sink. He didn't show. He was supposed to show last night. I didn't show. My guy promises that the plumber is coming today. We'll see. My boyfriend is angry while I'm just sad. I can't tell you how much sleep I've lost worrying about this project. I'm glad I "pulled the trigger", but I guess my feeling is that people I knew, people I let into my home, don't care enough to show up and give me a shower. These guys have worked on pretty big projects and I imagine working on a small bath with a new homeowner is very different.

They need to install a new ground wire from the fixture's bonding point to the box. If you HAVE a 3-wire nranch circuit (hot-neutral-ground) the fixture should be grounded by attaching to the grounded box or the ground wire itself. If you have an older circuit that is 2-wire (hot-neutral) it is not really going to make any difference though, you do not have a ground anyway. Note that some wiring methods (AC cable, metal conduit) use the armor or conduit as the ground connection and not a separate wire.

The basic layout should be 1) Your switch should be fed from the branch circuit. 2) The transformer should be in a junction box that is accessible - eg not behind a finished wall. The transformer will break eventually. 3) The power should run from the switch to the transformer on a continuous wire. 4) The wire between the transformer and the first light should be continuous. 5) The wire between the first light and the second light should be continuous. Any wire that you use before the transformer should be of the same gauge as the wire coming to the switch. Any wire after the transformer needs to be of at least comparable gauge to the wires that came in your kit, just longer. If that means you have to buy some additional wire for any of those runs, so be it. Even if the chance starting a fire with a low voltage wire is small, it still isn't something you want to splice and then hide inside a wall or ceiling. Treating 12V like normal voltage might seem like overkill, but you can easily start a fire with a 9V battery and some steel wool. Low voltage means that it won't kill you if you touch the wire. It doesn't mean that it can't create heat or a spark. If you are burying low voltage lights for landscaping, you don't really need to worry about catching the ground on fire. If you are going to put low voltage wires in your walls or ceiling or anything else that could burn, then you should take the same safety precautions that you would with any other wiring.

Thanks for the reply. Everything is working perfect as it was before. I did some more research after posting this, and I believe I have the following : 1x hot 1x switched hot 1x neutral. Being an older wire, there is no ground. The switch itself has a red and black wire going into it. I'm still trying to figure out why this is (the purpose), but can confirm that the black is always hot and the red is switched hot. Thanks.
