Supporting low voltage cable

[joeyos]

We were just shot down for using Romex staples to support low voltage HVAC control cable to thermostats in a wood structure. The AHJ says we can't use Romex staples. We can support off the cable. But not with tie-raps. Has to be velcro strap. Has anyone ever had this issue? This is in Maryland.

I meant we can support off the staple, not cable. But only with velcro.

Any code references. Sometimes insulated staples will say what they're listed for and if not smaller than a 14 2 might get complaints. But using them to support something else goes against that logic. See if just regular little 18awg lv T25 staples will fly.

The AHJ says no. He will not allow Cable ties nor staples. Not even staples with the plastic inside. This is for 18/2 cable. He says only velcro. I just want to get it right so I don't have to do it twice. (We are already doing 40 units over). I have never heard of this. Has anyone else? Does Maryland go by a different code than the NEC?

The authority having jurisdiction is being a bit ridiculous IMO.... What is his fear. If you want to get done go get those small insulated staples and be done with it,

 

[joeyos]

He has already warned that he will not accept them. And no tie raps as well elsewhere where the structure is all metal studs. He said only velcro. I'm trying to figure out what he wants in the metal stud section. A CJ6 with a velcro strap? Forgot to ask while he was there.

Was he wearing his clown outfit when he made these statements? Did he reference a code section or standard?

Sounds like design issues, not code issues.

How about 1-screw nylon cable clamps?

So, my foreman on the job just now informed me that it was not an inspector. It was an architect. That solves the ridiculous request. It was indeed a design issue that we were not made aware of. Thanks for the help all

Sounds like he is an IT guy. Ask him if he factored the additional costs for labor and material into the job.

I'm sure he hasn't. I could forgive its an oversight, but now I am paying to do it twice. Had he said he wanted it that way, I would have factored it in. Nothing I hate more than doing it twice

Has to be velcro strap.

It took me 14 years to learn how to ti3 my shoes. Then, someone invented velcro.

My family teases me because I have velcro sandals. Oh well. I'm an electrician, not a fashion icon.

Yes the newest trend, according to the July issue of Home & Design magazine.

I feel sorry for you having such a stupid person tell you how to secure a trivial tstat wire
