120/240 Volt, 1 Phase, 3 Wire Unit (3R Units):
Terminal post TO is the grounded (neutral) terminal.
For 120 volt current, connect the "hot" load wire to
either the Tl or T2 terminal. Connect the neutral load
wire to the TO terminal. Two 120 volt circuits are thus
available, with not more than 1/2 the rated capacity of
the set available on each circuit. Balance the load as
closely as possible (Figure 22).
For 240 volt current, connect one load wire to terminal
Tl and the second load wire to terminal T2. Terminal
TO is not used for 240 volt service.
CAUTION
If using both 120 and 240 volt current at the
same time, use care not to overload either
circuit.
