2. Take necessary steps to assure load is limited to
the capacity of the VANTAGE 500 CUMMINS 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 500
CUMMINS engine.
3. Install a 50 amp 120/240 VAC plug (NEMA Type
14-50R) to the double-pole circuit breaker using #6
or #4 conductor cable of the desired length. (The 50
amp, 120/240 VAC plug is available in the optional
K802N or K802R plug kits or by itself as T12153-9.)
4. Plug this cable into the 50 Amp 120/240 Volt recep-
tacle on the VANTAGE 500 CUMMINS case front.
