About this file

Written by GovTribe AI · Nov 5, 2026

This document is an electrical single-line diagram depicting the distribution system architecture for a facility with dual 1250 kVA generators (Gen #1 Tower and Gen #2 Tower), each with 14.8% and 26.7% impedance ratings and 0.022% resistance. The system operates at multiple voltage levels: 14.8 kV primary, 0.48 kV secondary, and 0.208 kV tertiary distribution.

The diagram illustrates a complex distribution network including two main switchboards (SWB SBA and SWB ESB), an automatic transfer switch (ATS) for fire pump operations, and ten 30 kVA step-down transformers (T-PLSA through T-PLSH, T-LSTJ, and T-CPP), each rated 0.48-0.208 kV with 4.8% impedance. The system includes multiple distribution panels (PNL LSA through LSJ, CPP, DPLS, and others) fed by copper conductors ranging from 2 AWG to 500 kcmil, with runs between 5 and 420 feet in conduit. Protection devices include GE and Siemens circuit breakers and disconnects with ratings from 50A to 1600A, Shawmut current transformers (1200/5 ratio), and various BGFL and ITE breaker configurations. The schematic notes specify that Circuit #136 is used for equipment duty calculations while Circuit #119, derived from KU Feeder data, is used for arc flash calculations, with an assumption of BGFL settings throughout the distribution system.
