Molded Case Circuit BreakersCause:
Cannot find equivalent to insulated connectors used with UL 489 and IEC comb bus bars. Need to know how the UL 1077 comb bus bars are wired.Resolution:
Field wiring is applied directly to the comb bus bar by inserting both the wire and the tooth of the comb bus bar into the same box lug of the Multi-9 breaker. Alternatively, an appropriately sized breaker applied to the busbar can be backfed to power the bus.
