I have always calculated commercial lighting as a continuous duty load for branch circuit and overcurrent protection sizing. I have also considered it to be continuous duty when calculating commercial services.
Today, an associate is arguing that it is not required to be multiplied by 125% for service calculations.
In looking at NEC 220, I can't argue with him. Anyone have input here? I have hit all continuous duty loads with 125% for load calcs for a long time. If I've been wrong, at least it's been an error on the conservative side.
Thx for any input and happy 4th to all
