T8.2 Transformer T8 SKM.pdf

This is a one-line electrical system diagram for Transformer T8 and Buildings 4, 5, and 6 at a VA Roseburg Healthcare System facility in Roseburg, Oregon, dated November 4, 2025. The diagram illustrates the electrical distribution architecture for the Electrical System Survey FY23 project and shows the interconnection between the utility primary service, transformer, and building electrical infrastructure.

The diagram depicts a single-phase primary T-8 fuse connection from the utility (UTIL: T8 Primary) feeding into a medium voltage transformer (Med Volt XFMR T-8) with a Site_XF T8 tap. The transformer output connects to a Site Panel Meters fuse unit, which then distributes power to Building 4 through a 200A GE main breaker, and to Buildings 5 and 6 through a Building 5 Meter Bank Feed. The distribution to Buildings 5 and 6 includes four meter main circuits (5A, 5B, 6A, 6B), each equipped with 125A breakers feeding individual panels. Building 5 utilizes a 400A GE main breaker on Panel 5A, while Buildings 5 and 6 employ 125A ITE main breakers on Panels 5B, 6A, and 6B respectively. The diagram is drawn to scale NTS and includes design and review approvals from personnel at Paradigm Engineering.
