About this file
This one-line diagram depicts the electrical distribution system for the Mental Health Outpatient Renovation B5 Project 52A5-19-305 at the Brockton VA Medical Center. It shows the location of existing switchboards, panels, transformers and loads, as well as new equipment to be installed including a dry type transformer and distribution panel. The project will establish infrastructure to support phased renovations, with Phase 0 work coordinating demolition and new construction. Loads removed from the existing switchboard will be reconnected to the new low voltage panel. Additional details include routing a new feeder to the chiller and providing breakers for mechanical equipment. A 400A circuit will serve a temporary building during construction.
