Answer Posted / electrical engineer kaleem 055
As my 5 years of experiance. I am still working in construction field as Electrical Engineer. Let me tell you 1 easy and good method to find the cable size for load , Earth cable size for load and to find the exact circuit breaker size which is require for load.
Always keep it in your mind that if load will 30kw or 20kw or 50kw etc always select the cable size 1 step down from the given load.Example for 30kw load cable size will be 25sqmm. and for 20kw it will be 16sqmm.etc
for earthing cable always load divided by 2. Example for 30kw load earth size will be 15 but in market 15 is not available so use 16sqmm yellow green cable and for 20kw load use 10sqmm cable etc.
Now for circuit breaker.
Always load multiple by 2 so that will be your mcb size.
Example if you are using 30kw load
30 x 2 = 60 so you will use 60 ampear mcb for 30kw load.And for 20kw use 40ampear breaker.
