I have two cases. Both are municipal.
Case 1
Case 2
This is what I am used to:
Case 1
- Utility provided 480/277 at the weatherhead.
- There is a main breaker between the utility and three pole transfer switch.
- Grounded conductor (neutral) was brought into the service disconnect and bonded.
- The generator (permanent) has circuit breaker.
- Customer is saying we have to run the neutral from the generator to the service and bond there.
- We have NO line to neutral loads. We ran a ground from the generator to the service.
Is the customer right about the neutral from the generator? If yes, can you please cite NEC?
Case 2
- Utility provided delta wye pad mount transformer with 470/277 on the secondary side. Meter is mounted at transformer.
- There is a main breaker between the utility and three pole transfer switch.
- The generator (permanent) has circuit breaker.
- Do we have to run the neutral from the transformer if we have no line to neutral loads? We ran a ground, not a neutral.
- Do we have to run a neutral from the generator to the service and bond there?
