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 rating over each 24 hr. period A 10% overload is available for 1 hour in every 12 hour of operation.

Standby powerVariable load. Limited to 500 hours annual usage up to 300 hours of which may be continuous running. No overload is permitted.

Emissions capabilityAll 4012-46TWG 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.

Notes:The battery capacity is defined by the 20 hour rateThe oil specification should be for the minimum ambient temperature as the oil will not be warmed by the immersion heaterBreakaway 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.
