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.
