Low voltage lighting waterproof grommet

ptr727November 17, 2013

Hi, I'm looking for some advice on how to connect my low voltage landscape lighting wire to an outdoor electrical box 3/4" NPT connector, keeping everything watertight.

E.g. the 3/4" screw plug on this box:

Something like these marine connectors:

But one that screws into the 3/4" female end of the electrical box.

Any advise?

I have basic electrical knowledge, but don't "get" exactly what you are trying to do. What and how many wires are going into the box? What is the mounting location/situation. Will the cover be plain, or will there be a switch in the box? I'm sure you don't need a marine-grade-waterproof-to-300-feet-depth connector ... especially being low voltage. If you haven't already bought the box, you might be better off with smaller openings instead of 3/4" ... tbd. Your best bet for avoiding water entry into the box is if the wires enter from the bottom. A 2-wire situation will be the easiest.
