10.1 4-Lead Reconnection
The following information illustrates the reconnection of
4-lead generator sets. In all cases, follow 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.
10.1.1 100--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 10-1. If the
installation requires a 100--120-volt, 2-wire system, use
a single-pole circuit breaker. See Figure 10-2. When
connecting stator phase leads together, size the output
lead (L1) accordingly to handle the amperage. Use a
jumper lead on the
line side of the circuit breaker to
balance the load of the generator set.
