NM cable staples

curt swartz said:
Very few NM staples are UL (or other NTRL) listed. None of the manufactures I use are. Dottie, Ideal, GB, Viking, etc.

The cable sizes and quantities are just recommendations. These recommendations are also based on NM cables from 60+ years ago when the cables were much bigger.

Just get a plan box/bucket or bag. Dump you favorite staples in. Write Electrofelon brand NM staples. Use with X size and X quantity NM cables.

Aren't they also picky there about stacking 3 cables under a staple? IIRC they say you have to use the long red ones for three. I love it, let some bureaucrat decide what sort of staple I need for the job. Why would you let me decide when I'm there and I know how hard the wood is and all??? Why does everyone hate electricians anyway? So sick of it.
 
I still want to know what the listing is? Do they test the staples with different sizes and combinations of wires. As I mentioned previously there are big variations between manufactures of NM cables.

Do they test the staples with soft, medium-hard and hard woods for pull out?

Seems dumb to list a staple. Why doesn't UL just say "LOL we don't list Staples, that would be dumb"

You can read all of the UL standards online for free. They use the same non-user friendly viewing system as does the NFPA.
