Larry,

Thanks for the suggestion (not to use the ground as neutral). I opened the wall and saw that I drilled right through the line romex-wire. The white was severed and the black was exposed.

I have not yet reconnected the outdoor flood arrays. I'll report back if I have a problem but I'm sure that was the source.

BTW: I wonder why every house is not built with the extra deep boxes! I had to replace the box to fit all of the wires as well as the switch unit. They are building in CAT-5, CATV and alarm in most new homes, they should install oversized boxes as well.

Thanks Larry
