General Inspection Prior to Operation

The DCA-400SPK generator has been thoroughly inspected and accepted prior to shipment from the factory. However, be sure to check for damaged parts or components, or loose nuts and bolts, which could have occurred in transit.

Extension Cable

When electric power is to be provided to various tools or loads at some distance from the generator, extension cords are normally used. Cables should be sized to allow for distance in length and amperage so that the voltage drop between the generator and point of use (load) is held to a minimum. Use the Cable Selection Guide (Table 10) as a guide for selecting proper cable size.

Circuit Breakers

To protect the generator from an overload, a 3-pole,1060 amp, main circuit breaker is provided to protect the UVW output terminals from overload. In addition two single-pole, 20 amp GFCI circuit breakers are provided to protect the GFCI receptacles from overload. Three 50 amp load circuit breakers have also been provided to protect the load side of the generator from overload. Make sure to switch ALL circuit breakers to the "OFF" position prior to starting the engine.

NOTE

ALWAYS consult with a licensed electrician for correct extension cord wire size.
