Steve, as long as there is a code (any code) requiring it, it is required. This is not being argued and has been pointed out earlier in this thread.
Saying the NEC doesn't require it -end of story-- is not an acceptable or responsible or complete answer.
It is if we are discussing just the NEC.
The point that the NEC doesn't require it is a fact.
We are not bound (or trying) to only discuss electrical code requirements from the NEC on this board, right?
We should discuss all applicable codes, but we should be acurate in what we are saying or enforcing.
