I am installing 6/2 Romex cable. I have previously installed 10/2 cable, and have installed larger cable for a subpanel feed. For my 10/2 wire, I still use staples, although it is those strap versions designed for bigger cable. For subpanel feeds, I use single hole metal straps, the same as the existing panel feed.

I can't seem to find a staple rated higher than #10 wire. I guess I could put it under single hole straps, but it would fit loosely, those are not really designed for cable.

Whats the correct answer here?

    How do you intend to feed a subpanel with 6/2? Combining both neutral and ground on the bare wire? You haven't been allowed to do that since the Eagles owned the pop charts. You need 6/3 cable. Mar 17 '20 at 21:08

You can use metal staples, which give you a bit more size flexibility. Just be sure to go forth gently and not crimp the cable jacket at all.

There are staples with plastic caps for that size cable, though.

Secure ... 8/3 - 6/3 non-metallic sheathed cable... to wood framing

  • I agree, but my box of bare metal 1/2 staples (shown here): homedepot.com/p/… say "Secures #14-3, #12-3 or #10-3 Romex cables and other NM cables", IE., #10 max. It does fit, I tried it. I want this install to follow code. Mar 17 '20 at 19:58
  • Are you asking me to find larger metal staples for you? Here are some.
