110.33 entrance to working space

[keelv]

We have a medium voltage motor control center (4160V) and trying to figure out if our layout is compliant with 110.33. The equipment is placed in the center of a control building with 4?-0? clearance on back and sides, and 6?-0? in front of equipment. Minimum clear distance per 110.34(A) is 4 ft.

Is one double door (opening outward), 8?-0? wide positioned in front of the equipment satisfying the NEC requirement? Is a double door considered two doors?

I?ve read all relevant posts regarding entrances/working space, and still can?t find a definite answer. Thanks for the help.

110.33A(1)a Where the location permits a continuous and unobstructed way of exit travel, a single entrance to the working space shall be permitted. I would consider a double door one exit.
