Answer / Mohd Tauhid

Calculating the insulation value of a conductor depends on various factors such as voltage rating, current carrying capacity, and power of the machine. The most common method used to determine insulation levels is by referring to industry standards and guidelines, such as IEC (International Electrotechnical Commission) or NEMA (National Electrical Manufacturers Association). These standards provide tables that outline suitable insulation materials based on voltage, current, environment, and other factors.
