OK, I did a search on this and read all previous threads and still don't know if the faucets have to be bonded. Some say yes, some no. Are faucets and drains part considered a "metal piping system" if supplied by non-metallic water lines? :confused:

Re: 680.74

If you have pursued the other threads, you have found no definitive answer. However, I will give you my opinion. No, faucets and short stubs are not required to be bonded if you have a non-metallic water system. :D
 
Re: 680.74

Thanks,Charlie, we are in agreement. Now this inspector is saying we have to run a #6 from the external lug on the pump motor to the grounding electrode system. I know this is not required by NEC but is it prohibited? Does it create a hazard where none exists? This is on a friend's job and I just don't want him to set himself up for litigation. He doesn't like to argue with inspectors. :D :D
 
Re: 680.74

Read the fine print print note to 680.26. I realize that 680.26 is for swimming pools, but the intent (equipotential bonding) is the same. After reading the FPN there, hopefully it will convince the inspector that not only is it not required, but in fact it is a wate of time.

As far as the faucets go, I think most inspectors ask for the motor to be bonded to them.

Also, where did the #6 come from? The requirment is "not smaller than #8 solid".

Thanks, Ryan. I have read and understand the FPN but like I said my buddy doesn't want to argue the point.

Why is that? I don't see how they could be considered a "metal piping system" but then I'm not the one in charge of definitions, am I? Do you require it on your inspections? Why or why not?
 
Re: 680.74

Yes, I do require it. Everything that I have read says that it is required. I wish I could think of some of the texts I have read that discuss it, but I'm at a loss right now.

Most of the installers that are around here are used to it from all of the other cities, so it is never an issue.
 
Re: 680.74

Buck, I fail to see what relevance 680.22(a)(4) has to this installation in either the 99 or 02 NEC. Neither mention water pipe. The applicable article is 680.74 2002 NEC where it does say all metal piping systems shall be bonded. IMO there is not a metal piping "system" present. The water piping is in some sort of flexible plastic which terminates in a copper tee to supply the faucets. IMO bonding this only creates a grounded point that would not be there otherwise. Along this same line, they run this plastic to every water outlet(sinks,etc.) and stub out the wall with copper. Does this copper need to be bonded? If so, why? Thanks :confused:

"Now this inspector is saying we have to run a #6 from the external lug on the pump motor to the grounding electrode system. I know this is not required by NEC but is it prohibited?"

My response was in reference to this statement by you.
