I have a situation where a 480/277V service entrance cable (from transformer) going through a handhole to feed a building (main service). The service entrance cable will be spliced in the manhole and extended to the building main service. The specification indicate to provide a driven ground rod and connect to 1/0 AWG bare but it doesn't say where needs to be bond to. I believe the other end of the wire needs to be bonded to the manhole metal cover and cover frame (no other metal components in the handhole) . My questions:
1. I'm not really sure if this will provide any fault path to trip the breaker. Not sure what is the proper way to bond the handhole cover and cover frame.
2. if the cover and the frame did not come with ground connection, what is the method of bonding?
Thanks,
