Q. We have motors that are interlocked, preventing them from being on at the same time. Do we still have to add them up for service and feeder calculations?
A. No. Where the circuitry is interlocked to prevent operation of motors at the same time, only those motors that operate simultaneously (and result in the largest current) need to be counted [430.24 Ex. No. 3].
