  • the total load current L1=122, amp L2=118 amp, L3=123 amp what is the main circuit breaker use for the load?

  • Answer:

    Circuitbreaker sizing is determined only by the the supply conductor size. The load requirement determines the conductor (wire) size. Begin with maximum current per phase, compute one way distance from breaker location to load (for delta service), derate for temperature and number of conductors per conduit, and 3% max Voltage drop to find conductor size. Select breaker to protect wiring. (BARE MINIMUM WIRE SIZE AWG#4)

You need one at least 123A...otherwise it would trip all the time.
