About this file
This file contains detailed electrical engineering drawings and specifications for a solar photovoltaic (PV) system installation at the Prescott Health Care Center VA facility located at 500 N US Highway 89, Prescott, AZ 86313. The drawings were prepared by REC Solar, Inc. in coordination with GLHN Architects and Engineers.
The technical drawings include single-line diagrams for three inverters, electrical site plans showing PV array layouts, metering/combiner sections, grounding details, conduit schedules, and comprehensive signage requirements. Key specifications include monitoring of circuit breaker trip status, providing visual open and lockable disconnect switches accessible from ground level, coordination with local utility requirements, and detailed conduit/wiring schedules listing conductor sizes, types, and voltage drop calculations. The system utilizes REC 240 PE (BLK) solar modules arranged in multiple strings of 14 modules each, connected through combiner boxes to three main inverters. The drawings provide comprehensive details for electrical contractors to properly install and interconnect the PV system components while meeting all relevant codes and safety requirements.
