I have heard a number of times that the "damp/wet" limitation on NM is because of the paper packing. I agree, it is the 21st century, why can't they use something that won't wick up water?
That would be NM-C I suppose.
My thought is, that would start nipping into the UF market and I bet UF is a higher profit margin product.
I wouldn't be shocked if someone said UF was actually cheaper to produce.
BTW has anyone seen NM-C? When I searched on the Southwire site a while ago it sent me to UF.
