About this file
This document is a technical drawing for a low voltage switchgear layout and pedestal at the Dworshak Fish Hatchery, prepared by the U.S. Army Corps of Engineers Walla Walla District. The drawing details a GSQ1 low voltage switchboard with specific electrical specifications, including multiple breaker cells with varying amperage ratings (800A, 2500A) and configurations. The layout shows a total width of 80.12 inches, maximum depth of 55 inches, and includes cells for a generator (G1), building feed, and spare capacities, with breakers rated at 65kA and featuring different trip unit settings like LSIG and LSI.
