amps rating it means load is one of the important procedure
for selecting the cable,breaker and transformer

Answer / anuj

mostly cable size is selected according to the load equipments,it is depend on the equipments, if my equipments is three phase ,so the current is difference from the single phase equipments,in a three phase circuit , 1 mm2 three core copper cable rating 4-5 amp.,and aluminium cable is taking only 2-3 amp. only.temperature of the atmosphere where we use it, is very important for the right cable selection
