This document is an electrical one-line diagram and panelboard schedule for an alert crew facilities project at an aircraft shelter. The drawing shows the main electrical distribution system serving three aircraft shelters with detailed circuit configurations and load calculations.

The system comprises two primary panelboards: HP5 (400-amp, 480Y/277 volts, 3-phase, 4-wire) and MPZ5 (208Y/120 volts, 3-phase, 4-wire). HP5 supplies major loads including a 62.5 kVA 400Hz converter serving shelters 1 and 3, bay door motors (two 9-horsepower motors per bay), and shelter lighting circuits with a total connected load of 244.3 kVA and estimated demand load of 199.7 kVA. MPZ5 serves lower-voltage circuits including roof obstruction lights (540 VA), security devices (500 VA), CCTV cameras (500 VA), IDS panel (1,000 VA), and PA system (1,000 VA) with a total connected load of 5.2 kVA at 100 percent demand factor. The electrical distribution system includes transformer T1 (75 kVA, 480V-208Y/120V) supplying the secondary main breaker for HP5, automatic transfer switches for standby generator power, and auxiliary equipment such as fire pump panels and entry control facilities. The panelboard specifications detail circuit breaker ratings, wire gauges, conduit sizes, and phase balancing across all three phases.
