2. 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 voltage which may damage appliances or
other motor-driven equipment and may result in
overheating of the Commander 400 engine.

3. 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.)

4. Plug this cable into the 50 Amp 120/240 Volt recep-

tacle on the Commander 400 case front.
