	Maximum continuous rated load for each leg of the
	240 VAC auxiliary is 40 amperes. Loading above
	the rated output will reduce output voltage below
	the allowable +/- 10% of rated voltage, which may
	damage appliances or other motor-driven equip-
	ment and may result in overheating of the Ranger
	305D engine and/or alternator windings.
