2. Take necessary steps to assure load is limited to the capacity
of the Vantage by installing a 50 amp, 240 VAC double pole
circuit breaker. Maximum rated load for each leg of the 240
VAC auxiliary is 50 amps. Loading above the rated output will
reduce output voltage below the allowable -10% of rated
voltage which may damage appliances or other motor-driven
equipment and may result in overheating of the Vantage
engine.
