Room Clearance Requirements for PZ4
Product Line:
Power-Zone 4
Environment:
Product Characteristics
Resolution:
10-ft. minimum ceiling height is required as measured from the base of the AR switchgear to the ceiling (i.e., 28.5-in. of clear space above the equipment) and includes arc blast, baffles, or plenum needs.
There is a minimum 3-in. space required around the equipment front, sides, or rear according to the ANSI C37.20.7 test criteria unless the equipment is directly coupled to other equipment. If the equipment is located against a Power-Zone house wall that opens up for rear access to the terminal cabinet, a clearance of 14-in. is required from the rear of the equipment for proper ventilation.
Additional space may be required for insertion and withdrawal of circuit breakers and to transfer to other compartments with a hoist or crane. In addition, required minimum clearances around switchgear are given in Article 110.28 of the National Electric Code or Rule 2-308 of the Canadian Electrical Code.
