I had no idea that anyone was concerned about the smoke toxicity of NM...very interesting. I'd always assumed that it wasn't allowed because it's such a wimp in the class of physical protection of the conductors. In this area it's allowed in the county, but not allowed in the city jurisdictions.

I run so little of it that I don't keep it in the truck. Part of it may be that it seems like cheap materials for low-bid work. It's not the type of business that I go after. When I run NM I feel like a weekend warrior, when I run EMT I feel like an electrician.
