VANTAGE® 500
Figure A5.1 Connection of the Vantage to Premises Wiring
1. Install the double-pole, double-throw switch
between the power company meter and the
premises disconnect.
Switch rating must be the same or greater than the cus-
tomer’s premises disconnect and service over current
protection.
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 amperes. Loading above the rated output will
reduce output voltage below the allow-
able -10% of rated voltage, which may damage
appliances or other motor-driven equipment and
may result in overheating of the Vantage 500
engine.
3. Install a 50 amp 120/240 VAC plug (NEMA Type
14-50) to the double-pole circuit breaker using
four-conductor cable of the proper size and desired
length. (The 50 amp, 120/240 VAC plug is avail-
able in the optional K802R plug kit.)
4. Plug this cable into the 50 amp 120/240 volt recep-
tacle on the Vantage 500 case front.
