NOTE: Wiring between generator and electrical appliances
1. Allowable current of cable
Use a cable with
a
allowable current that is higher than the rated input current of the load lelectrical appliance). If the
input current is higher than the allowable current of the cable used, tie cable will become excessively heated and de
teriorate the insulation, possibly boring it out Table 7-2 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 so that the input voltage
to the load (electrical product) decreases. As a result, the load can be damaged, table 7-2 shows voltage drops per 100
meters of cable.

Table 7-2
Voltage decrease indicates as V = lie x R x I x Z
R means resistance (S2/lOOm) on the above table.
I means electric current through the wise (A)
.Q,means the length of the wire (m)
The length of the wire indicates round length, it means two times of the length from generator to electrical tools.
