Written by GovTribe AI ·

This is an electrical one-line diagram for the VA Roseburg Healthcare System, a U.S. Department of Veterans Affairs facility located in Roseburg, Oregon. The diagram illustrates the electrical distribution system for Transformer T-8 and connected buildings 4, 5, and 6 as part of the FY23 Electrical System Survey (Project No. 653-23-104).

The diagram depicts a single-phase, 240/120-volt pad-mounted transformer (T-8) serving as the primary power source. Power flows from the transformer through a former meter base to a former meter center, which distributes electricity to four separate panels: Panel 4A (200A/2P MCB), Panel 5A (125A/2P MCB), Panel 5B (125A/2P MCB), Panel 6A (125A/2P MCB), and Panel 6B (125A/2P MCB). The diagram was designed by James Krumsick, P.E., LEED AP of Paradigm Engineering and was completed on November 4, 2025. The drawing is classified as sheet E1 T8.1 and is not drawn to scale (NTS).
