mains disconnect wiring question

15 years ago

I am installing a 100A meter socket with associated 100A load center. Between them I am installing a disconnect switch. This is a DU323RB from square D. It is a 100A knife switch/3 pole. The service is 120/240v three wire. My question is, do I only connect the hot legs to the switch and carry the neutral through to the load center? Or is the neutral switched as well? I have not found any information regarding this. This is not a residential issue, it is related to power for grain bins. thanks.
