Where an Uninterruptable Power Supply (UPS) is used in a system to ensure highly reliable power supply to an electronic system, occasional maintenance or repair of the UPS or its storage batteries may be required. Effecting this servicing while ensuring that the utility power continues to be supplied to the load may involve a Maintenance Bypass Assembly (MBA) comprising a plurality of manually-operated circuit breakers. The possibility of an incorrect actuation of such circuit breakers is precluded by the coordination of a plurality of electromechanically actuated circuit breakers in communication with a controller that may store a table of permitted state transitions and sequences for safe operation. Such operation may be confirmed by one or more sensors monitored by the controller.
