4614Switchgear Requirements

This section is concerned with isolation requirements and paralleling of systems. Isolation switches are addressed above in Section 4.6.1.1.

The owner/operator of the distributed generation will have interrupting devices sized to meet all applicable codes along with voltage protection and frequency protection. Where a disconnect switch is used, it shall be able to provide visible confirmation. Circuit breakers or other interrupting devices at the interface between generator and utility must be capable of interrupting maximum available fault current. For larger units, a redundant circuit breaker will be required for installations that can generate more power than they consume. This requirement is to cover the contention of a hung breaker. This may not be necessary if a utility grade or high quality circuit breaker is used.
