About this file
This is an electrical one-line diagram for an HVAC replacement and roof rehabilitation project at the Norwood Memorial Airport Air Traffic Control Tower (ATCT) facility. The drawing shows the complete electrical distribution system from the utility company connection through various panels and transformers across multiple levels of the facility (First Floor, Level C-1, C-2, and C-3, and Cab Floor/Roof).
The diagram details specific electrical specifications including a 75 KVA transformer, 208/120VAC 3-phase 4-wire systems, various circuit breakers and panels (including Main Distribution Panel, Equipment Room Panel, and multiple sub-panels), and detailed wire sizing specifications throughout the system. The scope of work is indicated by a cloud outline on the drawing, focusing on the portions related to the HVAC unit power connections. The drawing includes a comprehensive legend of electrical symbols and abbreviations, and was issued for construction on 08/22/2023 by the FAA Eastern Service Area Technical Operations division.
