Hello;

I just want to get some tips on the electrical faults. There are;

1. If live and neutral cables found shorted.
2. If live and earth cables found shorted.
3. If neutral and earth found shorted.

If this three faults above happen follow by number, what happen to the
electrical protection system such as ELCB, MCB, MCCB/RCCB or else.
Taken in real live system. Did the system explode?

Thanks
