NOTES : Wiring between generator and electrical appliances
1.Allowable current of cable
Use a cable with an allowable current that is higher than the rated input current of the load (electrical appliance). If the input current is higher than the allowable current of the cable used, the cable will become excessively heated and deteriorate the insulation, possibly burning it out. Table
2.Cable length
If a long cable is used, a voltage drop occurs due to the increased resistance in the conductors de- creasing the input voltage to the load (electrical product). As a result, the load can be damaged. Table

Table.
Voltage drop indicates as V= | 1 | x R x I x L | |
100 | |||
|
|
R means resistance ( Ω / 100 m) on the above table.
Imeans electric current through the wire (A). L means the length of the wire (m).
The length of wire indicates round length, it means twice the length from generator to electrical tools.
