Electric-vehicle supply equipment is considered a continuous load. At what percentage of its rating must the branch circuit and feeder be sized?
a.100%
b.125%
c.80%
d.150%
Giải thích
EVSE is a continuous load, so conductors and overcurrent devices are sized at 125% of the equipment rating. Sizing at only 100% ignores the continuous-load requirement, and 80% and 150% are not the applicable factors.
