Equipment bonding conductor

[SLC]

I have to install a 600amp-6 ganged meter enclosure with bypass and 100amp breakers on a commercial building. I intend to use parallel 350 kcmil cu service conductors and a 2/0 equipment bonding conductor. The problem I have is where to bond the service? The well feed main water line is plastic and pecks tubing is feed throughout the building. Also the building is a stick built, all wood structure. Any suggestions would be helpful.

Thanks,

Are you asking where to bond this service or how to ground this service?

If its grounding your asking about just drive one (or two if you can't verify 25 ohms or less) ground rod(s) run a 6 AWG cu or 4 AWG Al to this rod(s) and call it a day.

Is this a new or existing building?

If there is no copper or steel to bond then you don't have to worry about it. Just drive 2 ground rods and run a #6 copper wire to them.

And don't run a #4 AL conductor to an 8' rod. An aluminum GEC to a rod would require a 10' rod pounded in 8' since an AL GEC cannot be within 18" of the earth.
