Sizing

Outdoor cabinets should be sized or designed to provide:

• Unrestricted maintenance access to all installed equipment, wiring, cabling, and conduits by

field maintenance personnel.

• Placement of equipment at internal mounting elevations, relative to ground level, that will

provide field maintenance personnel with access to installed equipment at reasonable

working heights, for all or the majority of installed equipment. These requirements may be

met through the use of base extenders, bottom mounted battery cabinets, taller equipment

bays, or a combination of all of these design techniques.

• Sufficient space for the routing and termination of all internal wiring, cables, and conduits,

consistent with minimum bend radius requirements, and direction and/or manner of entry

into or out of the equipment cabinet.

• Sufficient space in front of, behind, above, and below installed equipment to allow for

unrestricted airflow within the cabinet.

• Sufficient reserve space in front of, behind, above, and below installed equipment to support

minor changes to installed equipment mechanical dimensions, as a result of changes in

vendor equipment utilized, or to support future vendor equipment design modifications.

Optional Cabinet Components

Integral AC Load Center

Integral AC load centers provide the ability to connect the outdoor cabinet’s commercial AC

power input directly to a power utility transformer. A typical load center will employ a meter

base, service disconnect, and breaker equipped load center, installed on the cabinet by the

manufacturer.

Advantages

Factory installation of an integral AC load center offers lower field installation costs; quicker

cabinet field deployment; improved site installation quality; and reduced instances of cabinet

damage caused by installation personnel unfamiliar with the cabinet design, construction,

penetration, and weather sealing requirements.

Disadvantages

Higher initial costs.
