This document contains a time-current curve (TCC) analysis for an industrial project with a reference voltage of 480V. It provides details on the circuit breakers, transformers, and cables in the system, including their ratings, settings, and damage/trip curves. The analysis evaluates the fault duty of a bus fault current at the generator circuit breaker CB-GEN2, which is rated for 2000A and has a short-time rating of 65kA.
