This is an image of an electrical panel box labeled "EPP-2" showing a standard electrical circuit breaker panel with two vertical columns of circuit breakers. The panel appears to be 208V/120V based on the label visible at the top. The breakers are numbered from 1 to 42, with handwritten labels along both sides. There are orange warning tags attached to certain breakers, marked "OLD NO REMOVE" and what appears to be a "LEAVE ALONE" note. The image likely relates to the HVAC and Fire Life Safety upgrade project at Portland ME Air Traffic Control Tower, as it shows existing electrical infrastructure that would need to be considered during the renovation work described in the contract opportunity.

This image provides important documentation of the current electrical system configuration that contractors would need to reference when planning work on the HVAC systems, particularly for the installation of new chillers, boilers, pumps, and building automation system components mentioned in the project scope. The clear labeling and warning tags indicate critical circuits that must be preserved during the renovation work.
