This specifications document outlines the technical requirements for a diesel generator procurement by the State of California (Contract P25-0815) to power equipment with complete installation services. The generator must be rated at 250 kW at 0.8 power factor with 480Y, 3-phase, 4-wire, 60 Hz voltage configuration. The unit shall feature a diesel engine operating at 1800 RPM with ADEM A4 electronic engine controller and EPA Emergency Stationary certification, along with IBC seismic and UL2200 compliance. The generator includes an LC5034 frame with single bearing design, automatic voltage regulator, PMG excitation system, and sound-attenuated enclosure rated at 75 dBA at 23 feet with aluminum construction. The fuel system must incorporate a UL-142 double-walled fuel tank with 660-gallon capacity providing 24-hour runtime at full load, complete with low fuel alarms and tank leak control.

Installation services encompass removal of the existing generator via crane, modification of electrical stub-up and concrete pad infrastructure, placement of the new generator with crane, electrical system installation, disposal of the existing unit, initial fuel tank fill, and comprehensive generator testing. The control panel must be NFPA 110 compliant utilizing a GCCP 1.2 digital control panel with remote annunciator panel capability and a single 600-amp UL-listed circuit breaker rated at 100 percent with load-sensing/instantaneous functions. Additional specifications include 24V lead-acid engine-starting battery with UL-listed charger at 10ADC maximum charging current, jacket water heater for expedited cold starts, seismic-rated integra isolators, critical grade exhaust silencer with flex connector and rain cap, and NFPA 110 alarm contacts.
