CONTROLS
CABLE SIZE:
Equipment damage can result from low voltage. Therefore, to prevent
excessive voltage drop between the generator and the equipment,
the cable should be of adequate gauge for the length used. The cable
selection chart gives the maximum cable lengths for various gauges of
wire which can adequately carry the loads shown.
ELECTRIC MOTOR LOADS:
It is characteristic of common electric motors in normal operation to
draw up to six times their running current while starting. This table
may be used to estimate the watts required to start “CODE G” electric
motors.
CAUTION: IF AN ELECTRIC MOTOR FAILS TO START OR
REACH RUNNING SPEED, TURN OFF THE APPLIANCE OR
TOOL IMMEDIATELY TO AVOID EQUIPMENT DAMAGE.
ALWAYS CHECK THE REQUIREMENTS OF THE TOOL OR
APPLIANCE BEING USED COMPARED TO THE RATED
OUTPUT OF THE GENERATOR.
