ECN Forum Forums General Topics of the Trade General Discussion Area Use of plastic cable ties

Tom, I looked at a box of staples and it was written on the box, the size of the romex allowed. When talking about cable ties they are not specifically rated to support NM, BX etc.

Article 100 states that the AHJ makes the call.

As an AHJ ( A**hole Having Jurisdiction ) I would never fail someone for using staples. Those staples have been around for many years and many people have used them safely.

Tom,

I looked up cable ties in the UL White Book. If they are listed ties, then "the evaluation of these products include consideration of the rated mecanical strength, maximum operating temperature, smoke and heat generation,corrosion resistance and weatherability..."

There is a requirement that the package be marked with the maximum load and thermal rating. The label on the one package of listed ties that I have is mostly missing & the only thing that I can make out is "suitable for use in air handling spaces" so I can't testify to a load rating in pounds. Seems to me at least some of the cable ties should have adequate strength to hold an MC cable or NM in place.

Anyhow, since you now know what this inspector expects, it probably wouldn't be worth fighting about.
