LESLIE Steam Generators have been  wired during assembly. 
Connecting  electric  power  supply  to  unit  consists  of 
connecting  correct  voltage,  phase,  and  amperage  power  leads 
to terminal strip or circuit breaker. Exact voltage, phase, and -
amperage requirements for unit can be determined from rating 
plate  affixed  to  jacket  of  unit,  or  from  Submittal  Sheet  and 
Wiring Diagrams supplied with unit
