This is an electrical one-line diagram for the ADAL Integration Support Facility at Peterson Air Force Base, Colorado, prepared by The Benham Group Architect-Engineer. The drawing, dated November 1, 1993, shows the electrical distribution system design for the facility and is designated as sheet 5E01 in the construction documentation set prepared under U.S. Army Engineer District, Corps of Engineers, Omaha, Nebraska contract DACA 45.

The diagram illustrates a complex electrical system featuring a 2000/2666 KVA transformer with 480Y/277V, three-phase, four-wire output serving multiple distribution panels, motor control centers (NMCC-1, NMCC-2, NMCC-3), and branch circuits throughout the facility. The system includes a ground bus with 100 percent neutral bus capacity, existing and new metal-enclosed 15 kV switchgear, and various protective devices including transient suppression units, circuit breakers rated from 20A to 4000A, and ground fault protection. The drawing specifies contractor requirements including the installation of dielectric unions after penetrating the Sensitive Area Restricted (SAR) area wall and the conference room wall, as well as the provision of an RF-filtered and shielded circuit breaker panel. The existing 15 kV service feeder to the facility is routed through concrete-encased ducts with spare ducts and uses 250 kcmil copper shielded EPR or XLP cables with 133 percent insulation.
