Does anyone see any flaws with this?
Metallic conduit on a customer-owned wood pole transitions to PVC underground and provides a solidly grounded service to medium voltage switchgear. The NESC says conduit, cable sheaths, neutral, etc. must be effectively grounded, which they define as bonded to an effectively grounded neutral conductor.
The cable sheaths and the conduit on the pole are bonded to the neutral on the pole and sized per NEC Table 250.102(C)(1). There is no ground rod at the base of the pole, because the GEC and MBJ are located in the switchgear.
