Grounding HELP

[pokercowboy]

I'm confused. I have a house with non metallic plumbing lines. I'm putting in a new 200 amp panel. Code requires all gas lines to be bonded. So am I supposed to run a grounding wire to the street side water line back to the panel and also use a grounding rod right below the panel. The water meter is about 75' away. Could I use the gas main as the ground for the panel with a bonding jumper around the meter. And then still use ground rod as supplemental ground.

You must ground the service to any approved electrode present at the structure being served. If there is no underground metal water pipe, no building steel, and no concrete encased electrode, ground rods can be used. Gas pipe is NOT permitted to be used as a gorunding electrode. See 250.52(B).

The gas pipe need only be bonded if it is LIKELY to become energized. See 250.104(B)

Cowboy,
Are you an electrical contractor?

just out of curiousity. is there any practical difference between bonding the gas line and making it a GE? I guess I can see if it was the only GE, but how is bonding it to an EGC any less worse then bonding it to the GEs?

Bob,

There is no difference, except that most gas utilities use a dielectric fitting at the meter to prevent the required bonding from making the underground gas line a grounding electrode.
