One hole straps as wire holders in panelboards

Question I just saw a video where they were using 1” one hole straps screwed into the panel instead of Ty wraps to hold the wires, majority of the comments were saying it was a code violation but never mentioned code is it a code violation or is it permitted. I don’t even know where to start looking in the NEC

There is no place to look in any previous code. Cable securing devices do not presently need to be listed.

Up coming editions will likely require these items to be listed

While there will be listing rules for the straps or other devices used to secure and support cable wiring methods in the 2026 code. There are no rules that address the securing of conductors within a panelboard cabinet in the current or 2026 code.

I've seen the images you mentioned. As long as there is no sharp edges involved really not much to use for rejecting it. I will say I have done this a time or two to help secure conductors in larger enclosures, usually have used PVC straps when doing so, for my own reasons but a metal strap with no sharp edges really no added hazards or performance issues than having the conductors in contact with the metal cabinet.
 
That’s what I was also thinking that it should be a none issue, an inspector might use needs to be listed for use and they are designed for strapping conduit.
Thank you everyone
 
I've heard the same concern here and there but never put much stock in it. NM has been fastened with metal staples since time began. Service cable held with staples, metal straps, etc. Overzealous hammering an issue at times but not that often.

Yeah I like PVC straps for this. Kind of necessary to do something when you have stranded wire to maintain some level of neatness. Sticky pads are a little quicker and easier, but I've not had good luck with those holding up for any length of time.

The only ones I have got to work are the 2x2 ones as they have four times the surface area and glue as the more common 1x1 ones.

I haven't seen those big ones, I could see those working much better. Of course clean the surface well with alcohol.

We use sticky pads in control panels, and if you just use the double sided tape, they will peel off given any sustained force or pull on them. We additionally anchor them using gel 2P-10 (which is really just gel super glue). A line down opposing sides, and a quick shot off accelerator to flash glue the clue, and you'd need a chisel to get them off.

I have used both one hole AC cable, EMT & rigid conduit straps to secure wires in large cintrrol.panels. Gave them a few wraps of silicone tape or quality tape like so scotch 33. While doing some work in an injection molding plant I had them give me a box of double sided straps made out of Lexan. Could not break them with an 8# sledge hammer. Had way too many of the smaller ty rab sticky back bases fall off, T & B made a 1" square sticky back base that stayed glued down for years.
