Hi I was just wondering
an irons flex had been twisted until the line and cpc is visible there was said to be a bang and I can see it’s burnt between the two.
my question is the 13amp fuse is fine but the rcd tripped and the mcbfor the circuit was down also.
i understand there was a earth fault so rcd tripped and as short circuit the mcb tripped...
But why didn’t the 13 amp fuse trip before 32a mcb and why did rcd and mcb both trip surely one is faster then the other?
