Number of poles and circuits in lighting distribution boxes

Branch Circuits, based on the 2023 NEC

You determine the required number of branch circuits by dividing the total calculated load in amperes by the ampere rating of the circuit [210.11 (A)]. If the load is calculated on VA per sq ft, the wiring system
