Allowable current of cable
Use a cable Wh 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.
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
7-2
shows voltage drops per
100
meters
of
cable.
