Egress Requirement for 1200A MCC with adjustable trip breaker.


We are designing an electrical room with a 1200A MCC with an adjustable trip main breaker that meets 240.6(C), set at 1000A trip. Can I consider the equipment to be "rated" at 1000A to avoid the egress requirement of 110.26(C)(2) - one egress path at each end of the equipment?

I think not. The rating of the equipment does not change when you choose to set the trip value to something lower.
