About this file
These are electrical engineering drawings for Building 5046 at the 126th Air Refueling Wing, dated 12/02/2013. The three-page document includes an electrical site plan, electrical power floor plan, and electrical lighting floor plan for a facility with multiple storage areas, offices, and an open bay. Key electrical modifications include: disconnecting and removing existing pad mount transformer and meter socket, providing new meter socket and CT cabinet, installing a new main switchboard (MSB) with service entrance rating, creating new ductbanks, and installing a new 5kV pad mount transformer with a 4-position primary switch. The floor plans detail the electrical infrastructure for various 48-768 square foot spaces such as unisex restrooms, storage areas, mechanical rooms, communications areas, and an open bay measuring 9,238 square feet. The drawings specify electrical equipment like exhaust fans (EF-1, EF-2) and provide detailed routing and coordination instructions for electrical installations.
