TP-5867 11/0260 Section 7 Generator Reconnection
7.2 Four-Lead (Single-Phase)
Generator Sets
The following information illustrates the reconnection of
4-lead generator sets. Always follow the National
Electrical Code (NEC) requirements.
7.2.1 Factory Connections, 110/220
Volts 50 Hz or 120/240 Volts 60 Hz
Generator sets are available from the factory connected
for 110/220 Volts 50 Hz or 120/240 Volts 60 Hz. See
Figure 7-1 for the factory connections.
Leads L1 and L2 are of different phases. Never connect
leads L1 and L2 together. After connection adjust the
voltage regulator to obtain the desired voltage.
Note: Use a circuit breaker manufacturer’s two-pole
circuit breaker. Two single-pole circuit breakers
do not conform to NEC requirements when
supplying a 220 or 240 volt load. This is true even
if they are mechanically attached together.

7.2.2 Reconnection Options
The following reconnections can be made using the
factory two-pole circuit breaker provided. It is the
responsibility of the individual performing the
reconnection to meet all the electrical codes.
See Figure 7-2 for four-lead reconnectable (single-
phase) generator set voltage options.

Voltage Connection Options
110 and 120 Volt Configurations
When connecting stator phase leads, size output lead
(L1) accordingly. Use a jumper lead with the same
ampere rating as the output lead L1 on the side of the
circuit breaker shown. After connection adjust the
voltage regulator to obtain the desired voltage.
Note: Electrical Codes: The 110 and 120 Volt
reconnection configurations require a jumper lead
on one end of the circuit breaker. This configuration
is acceptable per the National Electrical Code,
NFPA #70. Never jumper both the line and load
ends of the circuit breaker . A jumper on both
the line and load ends violates the National
Electrical Code by paralleling the breaker
poles. On occasion local electrical inspectors have
objected to a jumper on the load side of the circuit
breaker. It is the responsibility of the individual who
is reconnecting the output to make certain the
reconnection satisfies the local inspector. The
purchase and installation of a single pole breaker to
replace the two-pole breaker may be necessary.
Note: Jumper Sizing: Use a jumper lead with the same
ampere rating as the output lead L1 on the side of
the circuit breaker shown.
