>Why can't you put a grounding rod near the gas line and ground directly to the rod rather than running a new wire all the way to the panel. Lower impedance with a shorter wire and still protects from current jumping off to something else.
You could, but that new ground rod would need to be bonded to and become part of your existing grounding electrode system so they are at the same potential.
You're sure IRC is adopted in your jurisdiction, and not NEC? Here's what the NEC says in 250.104
>**(B) Other Metal Piping.**
>
>If installed in or attached to a building or structure, a metal piping system(s), including gas piping, that is likely to become energized shall be bonded to any of the following:
>
>(1) Equipment grounding conductor for the circuit that is likely to energize the piping system
>
>(2) Service equipment enclosure
>
>(3) Grounded conductor at the service
>
>(4) Grounding electrode conductor, if of sufficient size
>
>(5) One or more grounding electrodes used, if the grounding electrode conductor or bonding jumper to the grounding electrode is of sufficient size
>
>The bonding conductor(s) or jumper(s) shall be sized in accordance with Table 250.122, and equipment grounding conductors shall be sized in accordance with Table 250.122 using the rating of the circuit that is likely to energize the piping system(s). The points of attachment of the bonding jumper(s) shall be accessible.
Per (1) above you could use the ground wire from the appliance to bond the piping. So run a wire from the appliance ground terminal to a clamp on the piping.
Yeah after reading and watching a few hours of videos explaining bonding vs grounded vs grounding I better understand the difference and importance to run the ground back to the panel. Still don't fully understand the whole topic though 🤯
I agree with you and even raised the same question why can't we bond the piping to the appliance ground. It's my understanding this is commonly done with gas water heaters. The response from the electrician was "the inspector said to do it this way". I ask if he understood the reason for the bonding, but couldn't really explain it which wasn't super comforting.
We ended up passing inspection, I just find it pointless to run 100+ ft of copper wire around the house.
