Okay, I'm lost again with this one...
I got a question that said something like:
"In a class 1 div 1 location, what must be grounded?"
possible answers:
1) everything must ground ISOLATED
2) all permantly fixed, conductive surfaces must be grounded
3) all movable and non-movable surfaces must be grounded
4) any metal surface that can become charged must be grounded. (not sure about the wording of this last answer choice)
I found 501.30(a) that speaks of bonding, but nothing too specific. In 250.100 (bonding in hazardous locations), it only speaks of bonding non-current carrying metal parts being required to be bonded. I'm guessing it's answer #2... but im also deliberating with #3 -- all movable and non-movable surfaces and equipment must be grounded.
