Voltage Selector Switch<br />

The power available to each receptacle depends on the position of the<br />

voltage selector switch.<br />

120V ONLY Position<br />

When the voltage selector switch is in the 120V ONLY position, you<br />

do not need to spread the load over the receptacles. You must,<br />

however, make sure the load on any receptacle does not exceed its<br />

available power shown in the preceding table and the total load does<br />

not exceed 37.5 amps.<br />

120V/240V Position<br />

When the voltage selector switch is in the 120V/240V position, you<br />

must balance the load. Divide the load between the two sets of<br />

receptacles shown below. Balancing is necessary because each set of<br />

receptacles is powered by only one power producing circuit that can<br />

produce a maximum of 18.8 amps.<br />
