About this file
This document is a Single-Line Electrical Diagram for Buildings 204 and 205 of a construction project at a U.S. Department of Veterans Affairs facility in Lexington, Kentucky. The diagram illustrates the electrical distribution system for a Long-Term Rehab facility replacement, including power generation, transformation, distribution, and load management infrastructure.
The system includes a 500 KVA pad-mount transformer (12.47 kV to 208Y/120V, 3-phase), a 400 kW/500 kVA diesel generator set, and multiple automatic transfer switches (ATS) rated at 400A, 600A, and 800A with bypass isolation and open transition capability. The main distribution includes a 2000A main distribution panel (MDP), 205-MDP, and subsidiary distribution panels (NDP, CDP, EQDP) with ratings of 600A to 800A. The electrical infrastructure serves various loads including elevator systems (ELEV-1, 150A), equipment hookups (EHU units), air handling units (AHU units), and accumulators (ACCU units). The diagram specifies feeder cable requirements ranging from #2 copper conductors for smaller loads up to 5 sets of 600 kCMIL copper for the 2000A main feed, all installed in conduit. A comprehensive fault current schedule identifies 45 reference points with available short-circuit amperage ratings from 1,001 to 42,000 kAIC, and grounding provisions include water main connections, UFER foundation ground, building steel, and lightning protection. This is a 100% Construction Documents phase drawing dated December 18, 2020, prepared by Heapy Architects/Engineers for the VA Office of Construction and Facilities Management.
