This is an electrical panel schedule (Panel Designation: EPP-2) from a Schneider Electric panel dated 5/10/2016, showing the circuit assignments for a Y/120 VAC 3PH 4W system. The panel schedule details 42 circuits with various loads including HVAC equipment, pumps, lighting, and building systems.

The major loads include HVAC units for Room 305, compressor room equipment, pumps in Rooms 7 and 107, various lighting circuits including floor hall and electrical room lighting, and building systems such as elevator fire curtain, fire alarm, and boiler room equipment. There are several A/C units listed for the South and West walls, as well as some spare circuits and circuits marked for removal (Wall Quad #3 and Wall Outlet). This panel schedule appears to be part of the documentation relevant to the HVAC and Fire Life Safety upgrade project at the Portland ATCT, showing the existing electrical distribution system that will be modified during the renovation work.
