Great responses, but I fear that I didn't illustrate my idea completely...
At Pole: 10' Above grade RMC
Additional RMC to get to 24" depth
Metal 90
Transition to PVC Sched 80 RNC
(40', 1 bend, (probably metal,
unbonded per 250.86 Exception No.3
and then another 18')
Transition to RMC 90
RMC riser to
Meter enclosure (or to bushed entrance that is bonded to service cabinet.
I know that attaching a chunk of the raceway to a ground rod is grounding - the question I had was if anybody thought it neccessary to run an additional bare 6 AWG Cu with the conductors that was attached to bonding bushings (or soldered per ComEd) at the metal riser at the pole and at the meter enclosure.
ComEd originally told me they'd do the work, and that's what I told my customer - apparantly someone's mind got changed. Good thing I told them to expect an additional charge for the service drop/lateral installation. My bid's just for tearout, the panel and interior conduit so far.
I was told because it's classed as "commercial", the contractor is responsible for running the lateral.
As folks here (and the AHJ) have said - the PoCos follow their own rules, because it's on them, liability-wise.
