1. The choice of the electric cable.
The choice of the electric cable depends on the allowable current of the cable and the distance
between the load and the generator. And the cable section should be big enough.
If the current in the cable is bigger than the allowable current, it will become over hot and the cable
will be burnt. If the cable is long and thin, the input voltage of the electric appliance will be not
enough, causing that the generator doesn't start. In the following formula, you can calculate the
value of the potential "e".
The relations among of the allowable current, and length, section of the Insulating cable (single
core, multi-core) are as follow: (Presume that the use voltage is 220V and the potential is below
10V.
Ambient Temperature (25°C):Note: Changes in ambient temperature and changes in the wire and
cable laying methods will affect the carrying capacity of the wire and cable, The table above only
for reference.
