What is Fire Pump Circuit Breaker Sizing Guide about?

The document outlines the sizing recommendations for circuit breakers (CB1 and CB2) for a fire pump with a full load of 100 KVA and a full load current of 152A. CB1 should be rated at 1000A for 600% of the full load current, while CB2 should be rated at 320A for 125%-250% of the full load current. Additionally, it calculates the locked rotor current and checks the performance of the 320A CB under specific conditions, confirming it can handle the locked rotor current for approximately 60 seconds.
