NOTE
If installing a maintenance bypass, a minimum of two separate feeds with upstream feeder breakers, or a single feed with two
upstream feeder breakers, must be provided: one for the UPS or rectifier input breaker (RIB) (if installed) and one for the maintenance bypass
input. DO NOT use a single feed or a single feeder breaker to supply both the UPS or RIB and the maintenance bypass. If a bypass input
breaker (BIB) is installed in the maintenance bypass and a single-feed UPS is being installed, a single feed to the maintenance bypass is
acceptable for supplying both the UPS and the bypass.
