Where a branch circuit supplies continuous loads or any combination of continuous and noncontinuous loads, the minimum branch-circuit conductor size shall have an allowable ampacity not less than the noncontinuous load plus ____ % of the continuous load.
A) 50
B) 75
C) 125
D) 150

Question

The correct answer is 125% of the continuous load. This is based on the National Electrical Code (NEC) requirement that branch circuits supplying continuous loads must have a conductor size with an allowable ampacity of not less than the noncontinuous load plus 125% of the continuous load to safely handle the increased potential for heat buildup associated with continuous operation.
