OK, now I have to add...
How about a pool light with a 100' cord? That's underground for sure.
Recently on a resi elvator, the spec called for a 'safety switch' (lockable) to cut out the 120 volt control, and one to cut-out the GFI in the equipment room. The last comm on we did, a 3-pole disco for "all" 120 volt circuits in the 'pit'.
Electure's point was taken, and yes his install would be acceptable.
