About this file

This document appears to be an attachment detailing the electrical equipment layout and requirements for a project to replace two 12,470V to 480V transformers and install a new 200A panelboard in Building 27497 at Kirtland Air Force Base.

The key details are: The project requires replacing a 750 kVA and a 1500 kVA transformer, including their associated switchgear and instrumentation, with new copper-wound dry-type transformers. It also requires installing a new 200A, 480Y/277V, 3-phase, 42-space panelboard. The transformers provide power to several nearby buildings. The project is part of the broader federal contract opportunity FA940124B0003 issued by the Department of the Air Force Materiel Command Nuclear Weapons Center to complete this work at the specified location.
