7-1. Select Load Cable
Select the cable with proper gauge, based on its allowable amperage and the distance
between the generator and the machinery to be connected.
CAUTION : Damage to properties
 If the load exceeds the allowable amperage, the damage to the cable may
be damaged in overheating.
 If the cable is either too long or too small gauge, there will be greater voltage
drop between cables which brings voltage drop to loads. It may result in
reduced performance in the connected loads, malfunction, or damages.
< Note >

It is recommended to select the proper gauge and length of cable, in
consideration of the maximum 5% marginal drop only for the rated voltage,
between the terminals of loads and generator via the cables.
