10.1 Voltage Reconnection
The following information illustrates the proper
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.

Do not connect the load-side terminals of the circuit
breaker together when using a factory 2-pole circuit
breaker. See Figure 10-1. If the installation requires a
100--120-volt, 2-wire system, use a 1-pole circuit
breaker. See Figure 10-2. When connecting stator
phase leads together, size the output lead (L1)
accordingly. Use a jumper lead on the line side of the
circuit breaker to balance the generator set load.
