Some manufacturers specify the number of NM cables that can be placed under their product.most all I have seen states (2) 14/2 (2) 12/2. I recently found a brand that only says'"for securing 14/2 14/3 and 12/2 NM cables". Some time back I had a rough in turned down because I had 3 cables under 1 staple. AHJ stated install had to be per manufacturers labeling.If I placed them so I had (2) a(1) then I violated the 1.25" rule.Anybody here run into stapling issues?

It isn't an issue if you use cable stackers or just install 2 wire under one staple.

I use King brand staples that are rated for 3x 12/3 for all my romex (unless I use stackers). The regular staples are too small for my fingers to hold and hammer at the same time.

I prefer Thiel brand staples. Had to buy some imitation staples from the box store one Saturday, Some of them bent before the Romex was secure.

We use Briscon staples which are listed for two NM cables. Are staples even required to be listed? Briscon sells both listed and non-listed staples.

I like these. Never have to worry about over driving them. Hammer in very easily.

I've recently had an inspector claim that you have to install the staples to manufacturers specifications. In MA you have to use insulated staples. In order to put more than one wire under them you have to use the bigger staples with the red plastic insulation.
For ten years there was no problem with putting two 12-2 or 14-2 or even a 14-2 and a 14-3 under one staple. And in most towns it still isn't.
Oh well, I had been resisting stackers because they look sloppy and I prefer a solid support point before a box, but I'm getting used to them and it's obviously easier and quicker when installing three and four gang boxes.

I like to use the big grey staples for switch boxes, you can keep the cables flat and neat.:thumbsup:

With multiple cables above load centers I have done EMT one hole strap around the cables and zip tied the cables to the one hole strap. Or use a staples then zip tie the cables to it.
I don't know why some installers and/or inspectors get bent out of shape about the staples, how many under one, listed non listed....... I don't see what the issue is with multiple cables under one staple or strap. As long as the cable does not move and it i snot damaged because of the strap/staple, then I am OK.

How about an unlisted staple and a scrap piece of Romex sheathing

I was thinking the same thing,,,if I put too many wires or pinch one ,,,Ill be the one fixing it, besides AFCI is the safety net..
Sometimes I think its about selling a new thing. 2 wires under 1 staples has created lots of jobs.
That's what I did all the time. Hated it when someone wasted money on a box of stackers.
Sounds fine. Saves a trip to the truck to get zip ties.

Then you shouldn't sneeze on the staples!:lol:
oops..
Drive a staple in the center of a stud leaving it about an eighth inch proud, use that as an anchor. Wrap the zip tie around three or more romexes and through the staple and pull snug. You are now strapped and secured.

Tie the thermostat wire to the emt feeding the boiler. Tie MC cables together in heating systems with multi-zone 120v circulator pumps.
