TP-6053 7/0452 Section 10 Voltage Reconnection and Wiring Diagrams
10.1.2 100--120/200--240 -Volt
Configurations
This 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 10-1 and
Figure 10-2 for location). Select a circuit breaker
manufactured with a 2-pole circuit breaker. Two 1-pole
circuit breakers do not conform to NEC requirements
when supplying a 200--240-volt load. This is true even if
they are mechanically attached together. Since leads
L1 and L2 are different phases, never connect them
together.
