This is an electrical one-line diagram for temporary operating room (OR) trailers at the Veterans Affairs facility located at 10535 Hospital Way, Mather, California 95655. The diagram illustrates the power distribution system for three hybrid temporary trailers, each containing critical, equipment, and normal electrical panels rated at 200 amps at 208Y/120 volts, three-phase, four-wire configuration.

The electrical system incorporates multiple distribution boards and automatic transfer switches (ATS) to manage power flow between normal utility supply and backup generator systems. Key components include existing emergency distribution boards (EHS1001A, EHS1001B, NSH1001A, NSH1001B) with ratings up to 4,000 amps at 480Y/277 volts, switchboards (SWB-NORM, SWB-CRIT, SWB-EQ) rated at 600-1,200 amps, and step-down transformers (CRT, EQT, NT) each rated at 112.5 kilovolt-amperes converting 480 volts to 208Y/120 volts. The work scope includes providing and installing new breakers within existing distribution boards, routing feeders overhead from the electrical room to trailer panelboards, and establishing generator start signal connections. Feeder conductor specifications are detailed in six categories using copper conductors ranging from 3/0 to 500 kilocircular mil sizes with conduit runs from 2 to 3.5 inches. The document is dated September 30, 2025, and was prepared by AESUS design group for the U.S. Department of Veterans Affairs Office of Construction and Facilities Management.
