A small local EC (buys from big boxes) brought me a section of wire for an opinion. The labeling is:GCC-K Romex 14/3 with ground Type NM-B 600 volts (UL) 6/27/01 #2173/2616.
The conductors are THHN but the insulation is thinner than some THHN that I have and there is no filler in the jacket. It is about 25% smaller overall than some 14/3 w/g that I have. Since I haven't been active in homes, is this normal now or is this an import from China?
