tiring wires to cold supply lines, is this ok?
In some part of the wiring project on my basement. I saw the A/C guy tie the wire along the cold water supply line although they do clamp it to the ceiling joists as well in some other part..., therefore, I also do the same for a small part of my wiring, my question is, is it code compliance to tie wires onto cold supply line. I personally do not see anything wrong scientificly, but would like some advice from the expert, don't want the inspector to tell me that and have them revisit, as they charge per visit... expensively...

Which wire was the A/C guy straping to the cold water pipe. Or was it the condensing line to the AC?

The 24 volt wires that the AC guy uses for control are under different rules from the 120/240 volt wires in the rest of your house.

Let us know more about what is going on.

It is the 120/240 thick wire, red in color... definitely not the 24 volt wires you are talking about.

I would say that what he did was wrong. Your local inspector my let him get away with it. If I were you I would not follow his cue and do it that way. Let him get busted, but dont be the one to get busted yourself.

Electrical wiring is supposed to be supported from structural members. Studs and joists etc.

Why is the AC guy running the 120/240 for this. Does he have an applince installers licence, or is he breaking the law? Only qualified licenced people are allowed to wire into an electrical panel. What are the local laws that allow this guy to do this work?

Thanks jwhite for your information... I would probably remove the plastic band he used to clamping the wire onto the supply line. then add some metal clamps onto the joists for it... and do the same for those I did.. to avoid busted by the inspector...

Here in Ontario, Canada, anyone can do the wiring to the panel... the law said it has to be inspected... well.. when I installed the A/C two years ago when I bought the house... didn't think of that and didn't even know the procedure as I was at work while the A/C guy installing the A/C.... anyhow, I think the inspector, if smart enough, will charge me additional inspection fee for that and hopefully, nothing needed to be fix/change except for those plastic bands clamping we are talking about here...

thanks anyway...

I kind of don't know if I should really spend a few hundred dollars for this inspection hassle I am getting into.... anyhow... many people choose not to ... and I kind of choose the other way when I threw my dart...

Back before grounding rods were installed, common practice was to ground to the main water pipe. I would guess its still within code, but I'll wait for a pro to chime in.

Ground rods are suplemental. The main water pipe ground is still required.
