General Requirements in the NEC

Spaces for Equipment

Entrances for Large Equipment

Whether there is one entrance or two, if the entrance includes a door and the door is within 25 feet of the nearest edge of the working space for large equipment:

the door must be equipped with “panic hardware” (normally latched devices that open under simple pressure) and the door must open in the direction of egress.

The NEC does not require or assume that there will be a door. The working space may well be a part of a larger open area. However, for some equipment over 600 volts, a means of restricting access to only qualified persons may be required (see Section 110.31). When doors are used for access and egress to and from equipment rated over 600 volts, they must meet the same requirements as for doors used for access to and egress from large equipment rated 600 volts or less. However, when the equipment is over 600 volts, the requirement applies to doors within 25 feet of the working space without regard to the ampere rating or physical dimensions of the equipment.
