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 4-2 shows cables and their allowable currents for your reference.
2. Cable length
If a long cable is used, a voltage drop occurs due to the increased resistance in the
conductors decreasing the input voltage to the load (electrical product). As a result, the load
can be damaged. Table 4-2 shows voltage drops per 100 meters of cable.
R means resistance (Ω/100 m) on the above table.
I means 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.
