This is an electrical panel schedule specification document prepared by Prairie Engineers of Illinois, P.C. for the Illinois Department of Transportation District 3, detailing the electrical distribution modifications required for generator installation projects at the Ladd and Sycamore Maintenance Yards. The document presents comprehensive panel schedules for both facilities, specifying existing panels to remain and new panels to be installed with detailed circuit descriptions, amperage ratings, and breaker configurations. The Ladd Maintenance Yard requires modifications to multiple panels including a 400-amp main panel at Building D0390 (PP-1), a 200-amp main panel at Building D0222 (D0222 MDP), and various sub-panels throughout the facility. The Sycamore Maintenance Yard specifications detail panels at Buildings 205, 206, and associated structures with main breaker capacities ranging from 40 amps to 225 amps. All work must comply with the 2023 National Electrical Code, and the contractor is responsible for de-energizing panels during modifications and providing new ground bars and breakers as indicated on the schedules.

The panel schedules specify voltage configurations of 120/240 volts single-phase and 240/120 volts three-phase, with detailed circuit allocations for mechanical systems including unit heaters, air compressors, welders, furnaces, lighting fixtures, and facility support equipment. The document indicates that contractors should reference Sheets 5 and 6 for one-line electrical diagrams and the electrical specifications for additional construction requirements. Notes throughout the schedules indicate specific requirements such as providing new 2-pole 200-amp breakers, 100-amp main breakers, and ground bars in designated spaces. The design is dated May 1, 2025, with revisions through August 5, 2026, and encompasses the complete electrical infrastructure modifications necessary to support the generator installation and automatic transfer switch systems at both maintenance yard locations.
