Caution
:Electrical damages
If the load exceeds the allowable amperage, the overheating may damage the cable.
If the cable is either too long or too small a gauge, there will be greater voltage drop to loads, which may result in reduced performance in the connected loads, malfunction, or damages.
<Caution>
It is recommended to select the proper gauge and length of cable, with consideration of the maximum 5% marginal drop only for the rated voltage, between the terminals of loads and generator via the cables.
