bond gas pipe

[sanfcarolyn]

We would like to bond the gas pipe. Where should we attach the bonding clamp? The electrical main is ground to earth in the garage and also to the 1/2” portion of the copper water main in the hallway next to the garage. Last week Comcast (Xfinity) bonded the coax.

Possibly just a problem with Tapatalk?

Unsure whether rules are the same everywhere but in NYS, bonding of the gas line is directed in the following manner:

1) Gas meter outside - Bond the first 6" of rigid pipe entering the premises to the GEC.

2) Gas meter inside - Bond on the customer side, after the di-electric union provided by the gas company, to the GEC.

As I have been led to understand, in this area, the gas company places a "cathodic signal" onto the gas piping system for corrosion reduction. Bonding a gas line improperly would effectively eliminate this anti-corrosion signal.

Unless SF has special provisions, the EGCs, grounds, of the circuits supplying the gas appliances could be sufficient for bonding purposes.
