MINIMUM CROSS-SECTION OF THE POWER CABLES
The cross-section of the power cable must be chosen according
to the length of the cable and the type of installation, based on
the maximum current input of the air-conditioner and so as to
prevent excessive voltage drops (the power supply voltage must
be between ± 10% of the rated value).
The following table shows the minimum recommended cross-sec-
tions for the power cables.
