Project Scope:  

The short circuit study, coordination, and arc flash analysis was performed to determine the available short circuit fault current, the coordination of the circuit breakers, and the incident energy at each piece of equipment of all system components in the project.

 

The study includes normal power from the service entrance transformer to the main breaker, down through feeder circuit breakers on the 208-volt switchgear and distribution boards.

 

All Circuit Breakers, including branch circuit breakers, where evaluated and coordinated to identify

proper settings to be incorporated in the field. Settings and coordination characteristics were

identified on TCC Curves within the study. The study also included the generator standby

electrical distribution 208-volt three phase system, from the generator mounted circuit breaker

through the standby ATS, to the associated distribution boards in the building.
