8.1 Four-Lead Reconnection
The following drawings illustrate 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.
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.
See Figure 8-1.
requires a 100--120-volt, 2-wire system, use a
single-pole circuit breaker.
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.
