The engine generator system represents the design intent. Those listed are:

Caterpillar 600kW generator or approved equal
The engine generator system shall be in accordance with ASTM, ISO, NEMA, NFPA, UL, as shown on the drawings, as described in contract specifications, and shall conform to NFPA 99 and NFPA 110 requirements for Level 1 systems. Parameter schedule –
Power Rating: Emergency Standby
Voltage: 277/480V
Rated Power: 600 kW 750 kVA continuous)
Power Factor: 0.8 lagging
Engine Generator Application: parallel with other engine generators and a utility source Fuel: diesel
Voltage Regulation: + 2% (maximum) (No Load to Full Load) (standalone applications) Phases: 3 Phase, Wye
Each component of the engine generator system shall be capable of operating at 30.48 meters (100 feet) above sea level in a ventilated room which will have average ambient air temperatures ranging from a minimum of 32 °F in winter to maximum of 80 °F in summer. Engine generator shall have the following features:
Factory-mounted on a common, rigid, welded, structural steel base. Engine generator shall be statically and dynamically balanced so that the maximum vibration in the horizontal, vertical, and axial directions shall be limited to 0.15 mm (0.0059 inch), with an overall velocity limit of 24 mm/sec (0.866 inch per second) RMS, for all speeds.
The isolators shall be constrained with restraints capable of withstanding static forces in any direction equal to twice the weight of the supported equipment.
Shall be capable of operating satisfactorily as specified for not fewer than 10,000 hours between major overhauls.
Each engine generator specified for parallel operation shall be configured for automatic parallel operation.
The engine shall be coupled directly to a generator.
Minimum four cylinders.
The engine shall be able to start in a 4.5 ˚C (40 ˚F) ambient temperature while using No. 2 diesel fuel oil without the use of starting aids such as glow plugs and ether injections.
The engine shall be equipped with electric heater for maintaining the coolant temperature between 32-38 °C (90-100 °F), or as recommended by the manufacturer.
Install thermostatic controls, contactors, and circuit breaker protected circuits for the heaters.
The heaters shall operate continuously except while the engine is
