C04 - 6 - Drawings.pdf

This document is a collection of electrical engineering drawings and single-line diagrams for a facility infrastructure project. The drawings include detailed electrical schematics, site plans, and system documentation for what appears to be a multi-building campus or institutional facility.

The document comprises several key components: single-line diagrams for Buildings B-1 and B-3 showing distribution systems with transformers, circuit breakers, and load configurations; a comprehensive site electrical plan indicating the layout of electrical infrastructure across multiple buildings and grounds; detailed electrical schematic diagrams for basement electrical rooms and equipment connections; and various referenced notes regarding electrical specifications, conductor sizing, and installation requirements. The drawings reference existing utility connections, including connections to a 4160V switchgear and existing feeders, with provisions for new equipment such as generators, battery chargers, coolant heaters, and service receptacles. The documentation includes load descriptions, bus ratings, circuit designations, and mounting specifications. Plan notes address conductor routing, equipment grounding, utility connections per NEC standards, and specific technical requirements for electrical installations. The facility appears to involve multiple transformer sections, distribution panels rated at various voltages (480V, 277V, 120V systems), and coordinated electrical systems serving distinct buildings within the development. The drawings are dated April 1984 and include professional engineering stamps and approvals from the San Bernardino National Forest and related governmental entities.
