This document is an electrical single line diagram for the Tularosa Basin National Estuarine Research Facility. The diagram illustrates the complete electrical distribution system for the "MS-1" Partial Single Line and "BS-1" Single Line configurations, prepared by Malcolm Pirnie, Inc. as the engineer/architect with the prime contractor listed as Ancon Construction Company, Inc.

The diagram depicts a comprehensive electrical infrastructure including main service and distribution panels, multiple transformers rated at 1200A, 480V, 3Ph, 4W with 60 kVc capacity, and extensive branch circuits distributed across numerous panels and load centers. The system includes panelboards (LP-2 through LP-6), multiple exhaust fans, water heater controls, lighting circuits, test bays with dedicated electrical receptacles, and various specialized equipment connections. The diagram incorporates safety disconnects, overcurrent protection devices, and clearly labeled load calculations throughout the distribution network. A red circle highlights a specific section containing ACI-1 and ACI-2 (Air Conditioning units) with associated panelboards and distribution components. The document is dated December 2006 and includes standard engineering notes regarding proper installation of grounding, bonding, and adherence to applicable electrical codes and standards. The scale is noted as "Not to Scale."
