♥ The Effective Input Current should be used for the determination of cable size & supply requirements.
Motor start fuses or thermal circuit breakers are recommended for this application. Check local require-
ments for your situation in this regard.
♣ Generator Requirements at the Maximum Output Duty Cycle.
Reduced output ratings apply with the supplied 15A primary lead. To achieve the maximum rated output
& duty cycle ratings the 20A primary lead must be replaced with a larger primary lead as specified in
section 3.04. This must be carried out be a qualified electrical tradesperson.
NOTE
Due to variations that can occur in manufactured products, claimed performance, voltages, ratings,
all capacities, measurements, dimensions and weights quoted are approximate only. Achievable
capacities and ratings in use and operation will depend upon correct installation, use, applications,
maintenance and service.
