About this file

This document is an electrical engineering technical drawing for a low voltage switchgear one-line diagram, produced by the U.S. Army Corps of Engineers Walla Walla District for the Dworshak Fish Hatchery Electrical Upgrade project. The schematic depicts a complex electrical system with multiple 3200A and 800A thermal vertical bus configurations, including components such as generator (G1), metering current transformers, incoming neutral sections, and building electrical feeds. The drawing shows four 22" frame switchgear sections with various electrical protection and switching elements, labeled with specific technical identifiers like VAM 4C relay, LSIG trip units, and phase configurations (ØAØBØC), indicating a detailed electrical infrastructure upgrade for the fish hatchery facility.
