DIESEL GENERATOR RATINGS

Rating (See Notes) Description Time

1. Engine - Maximum steady-state active 0 - 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> Short-Time power output 2860/2800kW (running kW)

2. Engine - Maximum steady-state active > 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> Continuous power output 2600/2550kW (running kW)

3. Engine - Maximum instantaneous active 0 - 3 minutes Instantaneous power output (Cold) (running kW + starting kW) 2850kW

4. Engine - Maximum instantaneous active > 3 minutes Instantaneous power output (Hot) (running kW + starting kW) 3048kW

5. Generator - Maximum steady-state 0 - 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> Short-Time apparent power output 3575KVA (running KVA)

6. Generator - Maximum steady-state > 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> Continuous apparent power output 3250KVA (running KVA)

Notes:

DG Ratings 1 and 2: Engine short-time and continuous maximum steady state active power output (running kW) is denoted in the table as Non-derated Rating/Derated Rating.

• Non-derated rating for intake air temperatures less or equal than 90 °F.

• Derated Rating for either intake air temperatures greater than 90 °F or a combination of intake air temperatures greater than 90°F and engine cooling heater outlet temperature greater than 190°F.

DG Ratings 3 and 4: Engine instantaneous cold and hot maximum instantaneous active power (running kW plus starting kW) is denoted in the table as Non-derated Rating.

• Due to BFNs elevation is less than 800 feet above sea level with maximum intake air temperatures of less than 115°F, the maximum instantaneous active power output does not require derating for temperature.
