Circuit Breakers. 21 The BBS must be equipped with an AC Input circuit breaker that protects both the UPS and the 22 loads connected to the output. Should the AC input breaker on the UPS trip, it must allow the 23 UPS to go to inverter mode to power the intersection off of batteries. Should an overload 24 condition still exist when the inverter is energized the inverter must revert to its internal 25 electronic protection, preventing damage to the inverter due to the overload or short circuit 26 condition, on the output. Once this overload condition is cleared the inverter must energize and 27 power the intersection utilizing the available battery power. If the condition does not clear itself, 28 the inverter must stay in the standby mode until manually cleared by a technician.
