Disconnect molded case breaker


Senior Member
I have a conveyor system in a Class 1 div 2 area. The conveyor is driven by a 480 motor that has a local disconnect ( in the same area). I think it a Moeller. In talking with engineering it was impled that the local disconnect used a molded case breaker and would meet the area classification. I've contacted the mfg of the disconnect to see if it the disconnect is rated. Your comments are greatly appreciated.:blink:

See Section 501.115(B)(1). I suspect I know what engineering is attempting to apply and it's wishful thinking.
