i never had a problem with external fuse blown,
but i encountered a problem last month regarding my RCCB (the one in picture B).
power trip due to wallsocket faulty, but all MCB, RCCB, ELCB not tripped.
was puzzled at first, but when i tried turning ON/OFF the MCB & RCCB, the power is back on again.
it happened again afterwards, during a thunderstorm (and lightning),
no power due to lightning strike, but all MCB (picture A), RCCB & ELCB not tripped.
did some checking, and i assumed that my RCCB is faulty: there was no power in the house,
but the RCCB switch is in its 'ON" position (internal mechanism i guess).
changed my RCCB and it solved my problem, so far.
do you check your RCCB regularly (press the 'TEST' button to see if it can trip)?
faulty earth cable maybe ?but i encountered a problem last month regarding my RCCB (the one in picture B).

or maybe the fusebox got cable short circuit ?
outside fuse cant blow unless the current masuk ur house...
but since u off all the fuse, still can blow , maybe its time to check back all then wiring between main fuse to your fuse box...
inb4, i main hentam pull out and plug in main fuse near meter when fixing my new house, never experience it getting blown...
