About this file

Written by GovTribe AI ·

This document is a one-line electrical diagram for the PSERN (Puget Sound Emergency Radio Network) Maloney project, with project number T25-9019, prepared by LDC and checked by RBH on 08/05/25. The diagram provides a detailed electrical schematic showing the interconnections and power distribution for what appears to be an emergency communications infrastructure project, with multiple power sources, transfer switches, generators, and distribution panels. The diagram includes specific electrical ratings, circuit breaker configurations, and power flow pathways, indicating a complex electrical system design for critical communications infrastructure.

The one-line diagram includes technical specifications such as voltage levels, amperage ratings, and system configurations. The sheet contains flag notes indicating special considerations for service connections, generator interfaces, and potential future expansion. The diagram appears to be part of a larger set of engineering documents for the PSERN project, which likely involves upgrading or implementing a regional emergency communications network. The technical complexity suggests this is a significant infrastructure project with precise electrical system requirements for reliable emergency communication capabilities.
