Interesting, Skioutty.

I'm not an electrician, but I've had that experience as well. However, I've continued to assume that somewhere -- just not where I was -- there were waterproof boxes that worked. Hadn't thought about the condensation aspect, but given the air / dirt temperature differential, over much of the summer, that makes sense.

I'd be interested in your reaction to conduit grounds, and particularly, grounding via EMT and PVC coated metal flex. I have personally come to DESPISE conduit grounds.
