Remarks:
1.
Take the voltagedrop into consideration for selecting cable. Generally the voltagedrop
should be
<
5V and calculated according to following formula:
Voltagedrop=√3* Cable resistance ratio (Ω/KM)*Cable length (m)*Rated current (A)*10
-3
2.
If placed in plastic duct, the cable should be uprated by one level.
3.
The cable should be connected to the applicable cable and wiring terminal.
4.
The size of grounding cable should be the same as that of power cable when the size of
power cable is less than 16mm
2
. However, when the size of power cable>16mm
2
, the size
of grounding cable should not be less than half of it, but at least16mm
