Rating definitions
Baseload powerUnlimited hours usage with an average load factor of 100% of the published baseload power rating.
Prime powerVariable load. Unlimited hours usage with an average load factor of 80% of the published Prime Power over each 24 hour period. A 10% overload is available for 1 hour in every 12 hours.
Standby powerLimited to 500 hours annual usage with an average load factor of 80% of the published Standby Power rating over each 24 hour period.Up to 300 hours of annual usage may be run continuously. No overload is permitted on Standby Power.
Emissions capabilityAll 4012-46TAG ratings are optimised to the ‘best fuel consumption’ and do not comply to Harmonised International Regulation Emission Limits. More information on these statements can be obtained by contacting the Applications Department at Perkins Engines Company Limited.

Cooling system
Recommended coolant: 50% inhibited ethylene glycol or 50% inhibited propylene glycol and 50% clean fresh water. For combined heat and power systems (CHP) and where there is no likelihood of ambient temperature below 10 °C, then clean ‘soft’ water may be used, treated with 1% by volume of Perkins inhibitor in the cooling system.

Cold start recommendations
Notes:
� The battery capacity is defined by the 20 hour rate
� The oil specification should be for the minimum ambient temperature as the oil will not be warmed by the immersion heater
� Breakaway current is dependant on battery capacity available. Cables should be capable of handling the transient current which may be up to double the steady cranking current.

All tests were conducted using an engine installed and serviced to Perkins Engines Company Limited recommendations.
Applied load is a percentage of generator electrical output efficiency as published in the general installation section of this data sheet.
The information given on this Technical Data Sheet is for standard engines, and for guidance only. For ratings other than those shown contact Perkins Engines Company Limited, Stafford.
Initial Load Acceptance When engine reaches rated speed(15 seconds maximum after engine starts to crank)
2nd Load ApplicationImmediately after engine has recovered to rated speed(5 seconds after initial load application)
