wire staples

[Jim W in Tampa]

They make staples (uninsulated of course) 1" long. Somebody please give me a code or a reason you cannot put 3 flat 2 wire cables under one of those staples. So far this thread, I have seen some say they never exceed two, and I would like to hear why. Does your inspector say thats bundling? Ask him for a code to prove it is bundling and he wont be able to.

It is bundling but not always an issue with derating

Why can't you use tie wraps?

I've found that reading the label on any product can save headaches down the road.The staple container is required to list what it is approved for.2 12-2s layed flat under 1 uninsulated staple has never caused me a problem.3 wires under an uninsulated (king) staple is also a common practice.
