Webb3 apr. 2024 · The Rule of Thumb. Size the typical breaker current rating using an 80% utilization. This means, when the expected maximum current of the circuit where the breaker to be installed is 100A, then the breaker current rating must be 125A (100A/80%). In other words, always add 25% margin (100A X 1.25 = 125A). overwatch bn-054 pc
