Question - How To Determine The Number Of Lamps In Final Sub Circuit?
Answer -
If it is decided the current rating and already cable installed according to the rating of final sub circuit. and we want to know that how many light point will be on this final sub circuit.
Suppose for a normal lighting in a home,office or hall, the current rating of sub circuit or final sub circuit is 5Amp and supply Voltage is 220 Volts. then how many 100 Watt Lamps we can instal on that specific sub circuit. We can find the number of lamps by using this formula.
