•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.

•Install a 50 amp 120/240 VAC plug (NEMA Type 14-

50)to the double-pole circuit breaker using No. 6, 4 conductor cable of the desired length. (The 50 amp, 120/240 VAC plug is available in the optional K802R plug kit.)

•Plug this cable into the 50 Amp 120/240 Volt recepta- cle on the Commander 300 case front.
