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 7-2 shows cables and their allowable currents for your reference.
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 7-2 shows voltage drops per
100
meters of cable.
