I also have 480 and out of curiosity how would I wire that one to with a photocell. Hi, I am working on a 277/480 parking lot light, the light has a by-pass cap, I want to replace the by-pass cap with a 277 photo control, but I have a problem when I twist the photo cell in the head the fuse in the head will blow.

Meagan from Craft Habit decided to make her own version by painting an old nightstand and attaching Cain webbing in the inset.

How to you wire 240V input Do I hook 1 hot to 240V wire, other hot to 120V and the common to common. I have a system of 15 mercury lights with only a 10uf cap installed in the system for 277volts.

Or have you found a basic bedside table that could use a little personalization?

I don't see a ground wire, so how do you ground it?

Some of the lights work just fine this way but the others never light fully and then go out. I have a couple of questions about a 250 watt metal halide ballast.
