I don't know if this is the right place to post this, I know it isn't in the NEC but this is the situation.....
First of all, in NH, the gas man, plumber, or electrician can run the #6 bonding wire from the gas meter to a grounding electrode. So, the gas guy ran four #6 stranded, bare copper to a 100 amp sub panel in one of the apartment units and bonded them to the nipples at the four meters before it turns to CSST. I'm wondering if he should have gone to each sub panel, in each seperate unit.
Wha-da-ya think :confused::confused:

Are the gas meters grouped? Why not just run one #6 and hit all the meters with it? Also, it would be much better to hit the GEC outside and run to the meters rather than running the bonding jumper the way you described. That way, you are not bringing the wayward voltage into the dwelling.

1 they are far, far away.
2 too much snow.
 
They just say bond "it". They arn't clear on multiple feeds.

If you are bonding the CSST in accordance with the NEC then take a look at 250.104(B).

Unless you are using the EGC of the circuit that is likely to energize the gas pipe you can't connect the bonding conductor to a sub-panel.

250.104(B) requires you to connect the bonding jumper to the service equipment enclosure, the grounded conductor at the service, the grounding electrode conductor where of sufficent size, or one or more of the grounding electrodes used.

FWIW....In my area, the person installing the CSST is responsible for the bonding. As an electrician, it's not my job unless the installer wants to pay me to do it......
 
Agreed 100% on that one. The manufacturer recommends a #6 from service to manifold.

Greg, which CSST manufacturer are you dealing with.

I have seen some installation instructions that only require NEC compliant bonding, but that was about a year ago.

Actually, some of the CSST manufacturers use to say use 250.66 for the bond.
Omegaflex use to require the extra bonding but here is their latest product called counterstrike. The following is from their webpage

CounterStrike with the black, protective sleeve uses the same easy to install AutoFlare? fittings as conventional TracPipe? with the yellow coating. It is sold on wooden reels of varying lengths to meet the needs of the gas piping contractor. There are no additional bonding requirements for CounterStrike? imposed by the manufacturer's installation
instructions. Improved CounterStrike is to be bonded in accordance with the National Electrical Code NFPA 70 Article
250.104, the National Fuel Gas Code NFPA 54, and with any local requirements which may be in excess of the national codes.

I've seen a lot of manifolds installed a long way from the entry point of the CSST. I say the bond should be outside at the meter to keep objectionable voltage outside the dwelling.
