This document is a set of technical drawings and specifications for switchgear replacements at Marine Corps Air Station Cherry Point, North Carolina, under Work Order #7545551, designated as Phase 1 of a larger project.

The project encompasses the replacement of multiple electrical switchgears across two buildings at the facility. Building 137 requires the replacement of six switchgear units with the following specifications: one 480/277V, 2000A, 3-phase, 42 kAIC unit; one 208/120V, 200A, 3-phase, 65 kAIC unit; and four additional units rated at 480/277V or 208/120V with varying amperage and kAIC ratings. Building 138 requires two switchgear replacements: one 208/120V, 200A, 3-phase, 42 kAIC unit and one 480/277V, 1600A, 3-phase, 123 kAIC unit. The technical drawings indicate both existing configurations and modified configurations for multiple switchgear types (designated as "EB," "ED," "FA," "FB," "FI," "FJ," and "FK"), with detailed elevation and plan views showing dimensions, transformer connections, load/feeder conductors, and transition sections. General notes specify that new switchgears shall be NEMA 1 rated, molded case construction with square D equipment compatibility, include metering functions, and maintain dimensional consistency with existing equipment while allowing for proper installation clearance. The drawings include keyed notes addressing disconnection and reconnection of existing equipment, protection of cables, and proper disposal of existing apparatus.
