About this file
This is a set of electrical engineering drawings from NBP Engineers, Inc. for a project at Abraham Baldwin Agricultural College in Tifton, Georgia to replace main switchboards in Branch and Bowen Halls (Project No. 24094). The bid set is dated 12.05.2024 and includes detailed electrical schematics showing the main switchboard elevations and schedules for both buildings. The scope notes indicate the work involves disconnecting and removing existing MSB sections while preserving service entrance and sub-feeders, providing new MSB per elevation drawings, reconnecting service entrance conductors and sub-feeders, and reconnecting grounding electrode conductors.
The drawings specify technical requirements including a surge protection device (SPD) that must meet ANSI/IEEE C62.41 Category C standards with a 5-year warranty. All power outages must be coordinated with ABAC at least 10 days in advance through campus contact Tim Carpenter, with no outages exceeding 24 hours. For outages longer than 4 hours, the contractor is responsible for providing and paying for fire watch services. The switchboards operate at 208V 3-phase and 480V 3-phase respectively with 65 KAIC ratings. Existing conductors may be reused with field verification required for all breaker sizes prior to equipment submittal.
