Build Schedule

Standby: kVA @ 0.8p.f. These ratings are applicable for supplying continuous electrical power (at variable loads) in the event of a utility power failure. No overload is permitted on these ratings. Minimum output from alternators are peak continuous rated*

Continuous: kVA @ 0.8 p.f. Available for continuous electrical output. There is no hour limitation. 10% overload is available 1 hour in 12. The generating set and this specification is designed for environmental conditions of up to 27°C, up to 152.4m above sea level and up to 60% relative humidity.

Contact us for ratings outside the specified range.

Control System

Key start/stop with following meters:

  • Oil Pressure, Oil Temp, Motor Temp, Frequency, Volts and Amps
  • Shut Down for low oil
  • Emergency stop button
  • Output circuit breaker


  • Muffler, stainless steel exhaust flex (20 kVA and above) and clamps, battery and leads, day fuel tank.
  • Oil and coolant (within engine).
  • Circuit breaker and display for Amps, Volts and Frequency for all sets.


  • Mains failure control system instead of standard remote control system with mains failure relay, and static battery charger (mains supplied).
  • Changeover contactors in separate cubicle.
  • Constant potential (static) battery charger fitted to key start/stop system or remote start/stop system.
  • Jacket Heater – Thermostatically controlled heater supplied and fitted to maintain engine coolant temperature at approximately 40°C.
