INSPECTION/SETUP
GENERAL INSPECTION PRIOR TO OPERATION
Ground Power Tools
When using power tools or electrical equipment requireing
AC power from the generator, make sure power tool cord
has a ground pin or is double insulated as shown in Figure 6.
Figure 6. Ground Pin
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 (Table 4) as a guide
for selecting proper cable size.
Circuit Breakers
ALWAYS place the main, and GFCI circuit breakers in the
OFF position prior to starting the engine.
NOTICE
Double-insulated power tools and small appliances
have specially insulated housings that eliminate the
need for a ground. These types of double-insulated
power cords are designed so that no part of the device
will be electrically live even if the internal insulation fails.
DANGER
NEVER use power tools or equipment that do not
have a ground capability, the possibility exists of
electrocution, electrical shock or burn, which can cause
severe bodily harm or even DEATH!
