About this file
This is a technical addendum to RFP 20262020 issued by the City of Eugene, Oregon, specifying detailed electrical equipment specifications for Building 10 in the Community Renewable Energy Project. The addendum provides comprehensive technical specifications for an SB3 Switchboard (Alternative #1 MTS) comprising four sections designed for outdoor installation with flat roof configuration. The switchboard operates on a 480Y/277 volt, three-phase four-wire wye AC system with a 65,000 ampere capacity and features a 65C copper bus rated for 3,000 amperes incoming service. Section 1 functions as a distribution panel containing four 800-ampere branch breakers, one 200-ampere branch breaker, and two 100-ampere branch breaker spaces with associated cable specifications. Section 2 serves as the main service section equipped with a 3,000-ampere main breaker, dynamic arc-flash sentry maintenance mode, ground fault protection with ETU776 trip unit, and a surge protective device rated at 200 kiloamperes with SPD surge counter. Section 3 is configured as a bussed utility section containing provisions for Eugene Water & Electric Utility metering with 3,000-ampere capacity. Section 4 functions as an incoming bussed pull section with future connection provisions for both incoming and outgoing 3,000-ampere connections.
All four sections incorporate outdoor-rated construction with 4.125-inch front extensions, flat roof gasket-sealed enclosures (3R outdoor rating), copper ground buses, special shipping skids for large sections, and rear and section barriers. The switchboard includes 3,000-ampere interconnection components throughout, wire marker labels, and standardized bus configurations with top and bottom thru-bus arrangements. This electrical infrastructure is foundational to the renewable energy project's power distribution system, supporting the integration of the 120-kilowatt solar photovoltaic array and 440-kilowatt-hour battery energy storage system scheduled for operation by January 25, 2028.
