Well I might as well come clean, I live in a state that has a lot of faith in plain old NM and you know what? Our buildings are not burning down at an alarming rate and I have gone on very few service calls that NM was the cause of.

Here is one of our State amendments.

Mass. Electric Code.
Quote
334.10(3). Add an exception as follows:

Exception: Type NM, Type NMC, and Type NMS cables shall be permitted to be used in one and two-family dwellings, multi-family dwellings and other structures of Type I and II construction, provided that where such dwellings or structures exceed three floors above grade Type NM, NMC and Type NMS cables shall not be permitted to leave the floor or dwelling unit from which the cables originated.

So yes I am bias but I am also into facts and figures, not feelings.

If someone can point to some facts that the buildings in this state are more dangerous to the occupants in a Raceway building please point me to them.
