General Inspection Prior to Operation

Ground Power Tools

When using power tools or electrical equipment requireing AC power from the generator, make sure connecting (power tool) cable (Figure 7) has a ground as shown in Figure.

GDP-5H — PRE-INSPECTION

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 chart (Tables 4 and 5) as a guide for selecting proper cable size.

Never! use power tools or equipment that do not have a

NOTE ground capability, the possibility exists of electrocution, electrical shock or burn, which can cause severe bodily harm or even

DEATH!

					60 and 180 Hz Circuit Breakers
					To protect the generator from an overload, circuit breakers are
Figure 7. Ground Cables/Plugs					provided for both 60 and 180 Hz operation. Make sure to switch
					the these circuit breakers to the "OFF" position prior to starting
					the engine.
