Spoke with a friend at work today and he talked about his yard and garage getting flooded over the weekend: not surprising considering all the rain except for his having paid big bucks to have an elaborate french drain and sump installed.
The sump is deep, at least 6 feet, and it seems the installer placed the weather-tight outlet inside the sump as in below the level of the rim. My friend believes a brief power interruption may have caused the sump to fill. The installer having failed to install an "underwater outlet" the circuit tripped and the yard/garage flooded.
I looked briefly in the 2005 NEC and couldn't find the relevant prohibition, but I'm sure the outlet wasn't listed for underwater operation so I need some help finding the "don't do anything obviously dumb" paragraph.
Can anyone lend me a hand?
