Available Power
The power available to each receptacle depends on the position of the
voltage selector switch.
When the voltage selector switch is in the 120V ONLY position, you
do not need to spread the load over the receptacles. You must,
however, make sure the load on any receptacle does not exceed its
available power shown in the preceding table and the total load does
not exceed 27.5 amps.
When the voltage selector switch is in the 120V/240V position, you
must balance the load. Divide the load between the two sets of
receptacles shown below. Balancing is necessary because each set of
receptacles is powered by only one power producing circuit that can
produce a maximumof 13.8 amps.
