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!
