Any combination of
1
phase and 3 phase loading can
be used at the same time as long as no terminal
current exceeds the NAMEPLATE rating of the
generator. If no 3 phase output is used, usable
1
phase
output is 2/3 of 3 phase KVA.

FIGURE 14. CONNECTING LEAD FROM TERMINAL 63
120/240 Volt, Single Phase, 12 Lead: Terminal
con-
nection L0 can be the ground (neutral). For 120 volts,
connect the hot load wires to either the Ll or L2
connection, Figure 15. Connect the neutral load wire
to the L0 connection. Two 120 volt circuits are thus
available, with not more than 1/3 the rated capacity of
the set available on either circuit. If using both
circuits, be sure to balance the load between them.
For 240 volts, connect one load wire to the L1
connection and the second load wire to the L2
connection. Terminal connection L0 is not used for
240 volt service.

FIGURE 15. 120/240 VOLT, SINGLE PHASE, 12 LEAD
3 Phase, 4 Wire, Wye Connected Set; 12 Lead: The 3
phase, 4 wire set produces line to neutral voltage and
line to line voltage. The line to neutral voltage is the
lower voltage as noted on the unit nameplate, and the
line to line voltage.is the higher nameplate voltage.
For 3 phase loads, connect separate load wires to
each of the set terminals Ll
,
L2 and L3. Single phase
output is obtained between any two 3 phase ter-
minals.
The terminal marked LOcan be grounded. For
1
phase
loads,
connect the neutral (white) load wire to the L0
terminal.
Connect the black load wire to any one of
the other three terminals — Ll, L2 or'L3. Three
separate 1 phase circuits are available, with not more
than 1/6 the rated capacity of the set from any one
circuit.
If using
1
phase and 3 phase current at the same time,
use care to properly balancethe
1
phase
load,
and not
to exceed rated line current.
Figure 17 shows load connections for 120/208 voltage. Other
voltages are available from either parallel wye or series wye
illustration in Figure 13.
120/240 Volt, 3 Phase, 4 Wire Delta Connected Set; 12
Lead:
The 3 phase Delta connected set is designed to
supply 120- and 240 volt,
1
phase current and 240 volt,
3 phase current, Figure 16. For 3 phase operation,
connect the three load wires to generator terminals
Ll,
L2 and L3 — one wire to each terminal. For3 phase
operation the L0 terminal is not used.
For 120/240 volt, 1 phase, 3 wire operation, terminals
Ll and L2 are the "hot" terminals. The L0 terminal is
the neutral, which can be grounded if required. For
120 volt service, connect the black load wire to either
the Ll or L2 terminal. Connect the neutral (white) wire
to the L0 terminal. Two 120 volt circuits are available.
