Drawing 1.jpeg

This is an electrical wiring diagram/schematic from what appears to be a cooler mechanical system retrofit project for the Treatment and Detention Facility in Illinois. The diagram shows detailed electrical connections for multiple systems (labeled System A through F) that appear to be part of a cooling or refrigeration installation. The schematic includes main power connections (480V/3/60), a transformer (15 KVA), fusing details (15 AMP), and condenser fan wiring configurations (CF1, CF2, CF3).

The technical drawing contains a comprehensive legend identifying various components including circuit breakers, dual pressure controls, motor protectors, oil fail controls, and condenser fan motors. The diagram appears to be a factory wiring field wiring schematic that would be essential for contractors bidding on the cooler mechanical retrofit project to understand the electrical requirements and system configurations they would need to work with. The scale is shown as "1/4" = 1'-0"" and includes proper engineering notations and symbols throughout the schematic.
