• Take necessary steps to assure load is limited to the
capacity of the Commander by installing a 45 amp,
240 VAC double pole circuit breaker. Maximum rated
load for each leg of the 240 VAC auxiliary is 45
amperes. Loading above the rated output will reduce
output voltage below the allowable -10% of rated volt-
age which may damage appliances or other motor-
driven equipment and may result in overheating of
the Commander 300 engine.
