Rating definitions Prime power rating Variable load. Unlimited hours usage with an average load factor of 80% of the published Prime Power rating over each 24 hour period. A 10% overload is available for 1 hour in every 12 hours operation
Standby power rating Variable load. Limited to 500 hours annual usage up to 300 hours of which may be continuous running. No overload is permitted
Emissions capability All 2506A ratings are 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.

The oil specification should be for the minimum ambient temperature as the oil will not be warmed by the immersion heater
Breakaway current is dependent on battery capacity available. Cables should be capable of handling the transient current which may be up to double the steady cranking current.
