Article 250.104B states
Quote:
(B) Other Metal Piping, Where installed in or attached to abuilding or structure, metal piping system(s), including gas piping, that may become energized shall be bonded to the service equipment enclosure, the grounded conductor at the service, the grounding electrode conductor where of sufficient size, or to the one or more grounding electrodes used. The bonding jumper(s) shall be sized in accordance with 250.122 using the rating of the circuit that may be energize the piping systems(s). The equipment grounding conductor for the circuit that may energize the piping shall be permitted to serve as the bonding means. The points of attachment of the bonding jumper(s) shall be accessible.
Wouldn't all gas pipe have the potential to become energized? If I bond the structural steel would the gas pipe ,supported by metal hangers and fasteners, be adequate? Is it best to bond the gas pipe or is it something that is rarely enforced. I guess that it is best to have all metal to have the same potential to earth. I was thinking along the lines of a large commercial project, like a Lowes hardware or Home Depot. Would you treat the Gas Piping system like the water piping or sprinkler system. I worked on a Staples in Rhode Island and the inspector made us bond the street side and load side of the gas meter. I was an apprentice at the time and didn't ask enough questions regretfully. Thank you for your time and effort.
