Four-Lead Reconnection; 120-Volt Configurations - Kohler 6EKOD Service Manual

8.12 Four-Lead Reconnection

The following information illustrates the reconnection of
four-lead generator sets. In all cases, conform to the
National Electrical Code (NEC).
NOTICE
Voltage reconnection. Affix a notice to the generator set after
reconnecting the set to a voltage different from the voltage on
the nameplate. Order voltage reconnection decal 246242
from an authorized service distributor/dealer.

8.12.1 100- -120-Volt Configurations

If the installation requires a factory two-pole circuit
breaker, do not connect the load-side terminals of the
circuit breaker together; see Figure 8-18.
installation requires a 100--120-volt, 2-wire system, use
a single-pole circuit breaker. See Figure 8-19. When
connecting stator phase leads together, size the output
lead (L1) to handle the amperage. Use a jumper lead on
the line side of the circuit breaker to balance the load of
the generator set.

8.12.2 100- -120/200- -240-Volt
Configurations
The 100--120/200--240-volt configuration does not use
a jumper lead. If the unit was originally wired for straight
100--120 volt, 3-wire, remove the jumper lead (see
Figure 8-18 for location).

does not conform to NEC requirements for supplying a
200--240-volt load, even
mechanically attached together. Leads L1 and L2 are
for different phases; never connect them together.
