7-1. Load Cable Selection
CAUTION : PROPERTY DAMAGE
Cable burnout can occur due to generated heat if the load current exceeds
the allowable current of the cable.
The voltage drop between cables is large if the cable is excessively long or
thin, resulting in decreased input voltage to equipment using the generator,
thereby causing decreased performance, faulty operation and malfunction.
Select cable for use that has sufficient thickness and an allowable current possible for use,
giving consideration to the distance from the generator to the equipment using the generator.
< NOTE >
Select cable with a thickness that ensures that the voltage drop across the cable will be within 5%
of the rated voltage.
