About this file
This is a construction drawing document prepared by the Texas Department of Criminal Justice Engineering Services for the Crain Unit located in Gatesville, Texas (Coryell County), at coordinates 31.47197 N / -97.74000 W. The project, identified as MWR No. 02424027, involves the replacement of an emergency generator and automatic transfer switch (ATS) at the Crain/Hackberry Unit. The scope of work includes installation of a 155 kilowatt emergency generator rated at 208/120 volts AC, three-phase, 60 hertz with weatherproof housing; a 600-ampere ATS rated at 208 volts AC, three-phase, four-wire in NEMA 3R enclosure; a new 600-ampere docking station rated at 208/120 volts AC in NEMA 3R enclosure; and a new 600-ampere disconnect switch rated at 240 volts AC, three-phase, non-fused in NEMA 3R enclosure. The drawings are dated July 7, 2025, with plot dates of September 17, 2025, and include a site plan showing equipment location, one-line reference diagrams, and detailed system configurations.
The project specifications require all electrical work to comply with current National Electrical Code standards and Texas Department of Criminal Justice specifications, including Section 01 00 00.10 for project-specific requirements and Section 26 05 33 for conduit compliance. All circuit conductors must be copper THWN-2, with conduits installed per NEC standards. The existing transformer bank consists of three 75-kilowatt units rated at 4160/2400 to 208/120 volts AC. The engineering drawings were prepared by Eduardo F. Viana, a Texas Professional Engineer (License No. 129756), with construction authorization noted as of September 17, 2025. Brand or manufacturer references in the specifications are descriptive in nature and allow for A/E-approved equal alternatives that meet the stated specifications.
