I'm the electrician for a hvac contractor and new rules have come into effect stateing that trac pipeing (or flexible gas pipeing) shall be bonded. the only problem is which end, what size bond wire, and where to bring it. The inspectors want it but can't give us an answer either.
 
look at 250.104 (B), it is already considered bonded the equipment ground of the circuit that could engergize the gas pipe, there is a bulletin that is going around from the CSST companies about bonding requirements for there piping, unless your area adopted those requirements you are code compliant, and if it is a local ordinance the inspectors should be able to give you an answer
 
It's in the pipe manufacturer install instructions. You bond the galv pipe or the flex pipe connector with a ground clamp and a #6 cu.
 
Trac piping special bonding does not fall under the NEC. You need to size your wire to T. 250.66 and connect it at any end of the pipe connector but not the pipe itself. A brass ground clamp works well. I usually bond it at the point of entry into the building because there is usually a short piece of black iron there to bond to.

To an electrician those instruction are nothing more then a suggestion. The NEC does not apply to the installation of non-electrical equipment so 110.3(B) is out of the picture.


In my area they stopped allowing the installation of the flex pipe until they work out how to handle it.

that is probably the best idea, if all the towns did the same it would force the manufacturers to come up with a solution, I don't think the manufacturers know the best way to handle the bonding of there own product, it makes me wonder if this piping missed a test before it was put on the market
 
New York State does not have a state wide license for electricians, some local jurisdictions do not even require a license person to perform electrical installations.

Yet, we have a new STATE wide law the requires all installation of gas, including installations with no CSST to follow the new code...go figure.

So, if you are doing work in NY, you should go to the state site and download the 3 pages of requirements. (there are actually 6 pages, 3 pages are residential requirements, 3 pages are commercial requirements - they are identical)

here is he link for NYS requirements

It is a state wide ban so it is much more effective..

Effective as of December 1, 2008
The Board of State Examiner of Plumbers and Gas Fitters at its regularly scheduled meeting held on November 26, 2008, voted to temporarily rescind the approval of all Corrugated Stainless Steel Gas Piping Systems (CSST) in the Commonwealth of Massachusetts until such time as the Manufactures' recently amended bonding requirements are resolved by the appropriate Authorities Having Jurisdiction.

Gas permits issued prior to the above effective date for the installation of CSST Gas Piping Systems are NOT affected by this decision.

The CMP discussed bonding of CSST, but no rules were adopted.
Here are the rules adopted Dec 31 2008 in Washington State:
104(B) Bonding ? other metal piping.
(10) For flexible metal gas piping, installed new or extended from an existing rigid metal piping system, either:
(a) Provide a copy of the manufacturer?s bonding instructions to the inspector at the time of inspection and
follow those instructions; or
(b) The bonding conductor for the gas system must:
(i) Must be a minimum 6 AWG copper; and
(ii) Terminate at:
(A) An accessible location at the gas meter end of the gas piping system on either a solid
iron gas pipe or a cast flexible gas piping fitting using a listed grounding connector;
and
(B) Either the service equipment enclosure, service grounding electrode conductor or
electrode, or neutral conductor bus in the service enclosure.

You would be safe to follow the above rules.
 
Thanks for all your suggestions. We have a rep. from a trac pipe manufacturer
coming to give a seminar on just what they require, (2 local inspectors will be in attendance, they are just as confused {maybe even more than usual}). Then at least we'll be on the same page.

Last time we had the rep here they were not on the same page with their own website. We got a bunch of BS
