About this file
This document is an electrical one-line diagram and associated notes for Building 60 construction work. The diagram illustrates the electrical distribution system including switchboards, panelboards, transformers, and related equipment connections throughout multiple floors (first floor, mezzanine, and second floor) of the facility.
Key electrical components and requirements include: installation of a fire pump feeder with separate switchboard vertical section below the slab within a concrete encased ductbank, extending to the fire pump room; provision of a Shark 270 meter with associated current transformers mounted on existing steel slotted strut support; Category 6 cable in 1-inch RGS conduit between the meter and existing network switch WCO3004 (approximately 20 feet); connection of existing Duraline connection to a relocated exterior receptacle with ground fault protection; temporary power provision to Building 60 construction trailer via existing transformer (assuming 100A, 120/208V, 3-phase); reinstallation of salvaged exterior receptacle serving existing trailer 2; adjustment of current setting to 1,140A (.95X); provision of service entrance available fault current label; and provision of conduit and wire for generator controls, block heater, monitoring, and battery charger. The document references panelboard schedules (EP601-EP604), electrical site plan (ES101), and mechanical and plumbing equipment wiring schedules (EP503-EP504) for additional specifications. Two Contract Line Items (CLIN 004) address exterior receptacle relocation and reconnection tasks, with coordination required with the Contracting Officer on exact locations.
