What is the Procedure for selecting a Cable, Breaker and
Transformer for particular load.
Answer Posted / 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
