gas pipe bonding

[GerryB]

250.68 says our interior metal water piping ground should be within 5 feet of entering the building. Does gas black pipe have to meet that requirement.

That's not exactly what 250.68 addresses but to answer your question, black iron gas piping can be considered bonded by the equipment grounding conductor connected to a gas appliance or by other means spelled out in 250.104(B) if the appliance ground is not present. If you do bond it with a jumper to another electrode or the service, it can be connected at any point in the system although some inspectors like to see it at the water heater.

No not for black pipe. CSST does have some additional bonding requirements but they are not part of the electrical code. As Augie stated the EGC is what bonds the gas pipe.

No, you just need to make the bond on the meter side of any yellow CSST.
