Bob,

But without some facts to show it is unsafe what is the problem.

I agree. I wanted to bring this one up because MA did cite a very safe history of NM use, hence the suspended ceiling ammendment in the MEC. I'm pretty sure I read that in the ROPs, but I can't quite remember.

Correct me if I am wrong, but didn't the MEC also allow NM to be used in buildings of any height long before the '02 NEC made the change?

Since I am not from MA I am going by hearsay and may be totally screwing this one up. [Linked Image]

I will admit I am not comfortable pushing a 12/3 out of the way with 480 volt, 3 phase live in it.

I don't think anyone would be. [Linked Image] Nobody should feel comfortable pushing any live cable around, MC, AC or otherwise.
