Determine the diameter of the electrical wiring in accordance with the capacity of the AC (PK)

Diameter electrical cable that is used in accordance with the capacity (PK) AC:
         PK AC Cable Diameter
AC 1/2 - 3/4 PK = 600 Watts = 1 mm2
AC 1 - 1.5 PK = 1170 watts = 1.5 mm2
AC 2 - 2.5 HP = 2570 watts = 2.5 mm2
Cables that are commonly used: NYM
Voltage: 300-500 Volts
It has 3 wires
Cable usage that does not comply with the specifications will be harmful to safety. Examples AC 2 PK using 1 mm2 cable. Then the cable is too large to accommodate the flow, the cable will be hot and can cause fires.
Usage 3 cable, which is useful for eliminating ground wires and ground the induced current electrical shock.
