2020 B Vault 1 Line.pdf

This document is an electrical distribution system single-line diagram (E-103 drawing) prepared by Fellenzeri Engineering LLP for an electrical distribution building's Vault 'B', part of an Arc Flash Study. The comprehensive schematic details the intricate electrical distribution infrastructure, showing multiple switchgear, bus connections, transformers, and circuit breaker arrangements across various voltage levels and distribution paths. The drawing is marked as 100% documents and includes contact information for the engineering firm's Poughkeepsie and Middletown, NY locations, with the project number FE# 19-401. The diagram provides a technical visualization of the electrical system's topology, critical for understanding power flow, protective device coordination, and potential arc flash hazard analysis.
