#6. Why are we limited on the number of overcurrent protection devices on the supply side of a lighting and appliance branch circuit panel board to not more than two main circuit breakers or fuses?
?FPN on Article 230.71(B) references Article 408.16(A) for overcurrent protection devices of a lighting and appliance branch ciruit panelboard. This, latter Article restricts the number of circuit breakers or the number of fuses to two, based on the fact, that use of single pole units is permitted on a multi-wire circuits. Lighting and appliance branch circuit panelboards are intended to supply 3 wire, single phase power to individual lighting and appliance branch circuits.
