yo, fittering about here tell me if im right.
example: identifying the minimum size of cpc required to ensure protectionfor copper conductors protected by say 50A tybe b mcb to .
so 250x250x0.4=25000 sqare root= 158.1/ 115=1.37..
so is this correct by multiplying type b by 5?
and my 50A is ok with 1.5mm cpc??
