26 Reconnection/Adjustments TP-6335 9/04
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. If the installation
requires a 100--120-volt, 2-wire system, use a
single-pole circuit breaker. See Figure 8-2. 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.

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 8-1 for location). Select a two-pole circuit
breaker. Application of two single-pole circuit breakers
does not conform to NEC requirements for supplying a
200--240 volt load—even if the breakers are
mechanically attached. Leads L1 and L2 are for
different phases—never connect them.
