I am installing a shower light as part of my bathroom renovations, but when I access the wire at the light switch box there are two cables, each with a black (live), a white and a ground wire. The two white wires are connected to each other, the two grounds are connected to each other and the two black wires go to each terminal on the switch. Where do I "tap in" my new three-wire cable? I am quite happy to have the shower light go on at the same time as the existing bathroom light.

Is this known as series wiring, because I think my upstairs hall light is also on this circuit?

Please help.

Thanks,

joed

You could connect the shower light to the existing bathroom light. You don't have to go to the switch box unless that is the prefered location. At the existing light you should have 2 blk, 2 wht, and 2 gnd. Connect you new light so that you have 3 blk, 3 wht, and 3 gnd. Your light will have to be a waterproof fixture rated for intallation in wet locations is you are installing in the shower.

I just installed a waterproof shower light. It's a recessed fixture that mounts between the ceiling joists, and it has thermal-protection in case it gets too hot. It has a cork gasket between the glass (not real glass) and the fixture housing. Oddly enough though, there is no gasket between the fixture housing itself and the ceiling material. The lamp fixture just slides up into place inside the outer housing and snugs against the ceiling. So, while the bulb itself seems reasonably well-protected, I'd think some water vapor might get through to the backside of the entire housing where the wires are. Is this anything to worry about?

When I bought this waterproof fixture, I was expecting to see something that was almost dunkable.
