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

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.

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.
