I'm having my Electrician wire 9 1.5HP 3Phase roof fan motors. There is a little problem. My boss wants me to have the motors wire this way. From a 60amp breaker go to a Motor Stater with 10amp heaters then to a service disconnect switch then to the motor but from the first Motor Stater he want to branch to the next motor starter and from that one to the next one and so on. Is this legal?
