Appendix I - Transformer and Switchboard.pdf

This document is an appendix detailing a Siemens electrical switchboard and transformer system, specifically for a Department of the Army Corps of Engineers project at Lakehurst Naval Base. The technical documentation includes a Siemens SB3 switchboard rated at 34.5 kV, with a 2000 kVA transformer configured for 480/277V, 60 Hz, 3-phase Wye AC power. The switchboard, manufactured in January 2014, is a deadfront design with a 3R enclosure type and a short-circuit current rating of 65,000 RMS symmetrical amperes at 480 volts maximum. The equipment includes multiple safety warnings about shock and arc flash hazards, emphasizing the need for appropriate personal protective equipment (PPE) when working with the system.

The appendix contains detailed technical specifications and identification labels, including a Sentron PAC4200 power monitoring device that tracks electrical consumption with on-peak and off-peak kilowatt-hour measurements. The system is part of a larger electrical infrastructure upgrade, likely for the Manufacturing Lab Addition project at Joint Base McGuire-Dix-Lakehurst in New Jersey. The documentation provides comprehensive technical details about the electrical equipment, including manufacturer information, voltage ratings, manufacturing date, and critical safety instructions for maintenance and operation.
