wujud ke MCB yang ada mechanism untuk tunggu beberapa minit/jam untuk sambung supply balik?
takpun MCB yang boleh check if  tak ada faults dalam circuit dan sambung balik if tak ada?
CB pun boleh.

Kalo ada pn, dia x panggil circuit breaker kot - recloser
Biasanya kt sub-station je pakai...

Klo hi/medium-hi wealth residential housing, commercial, etc.
biasa ada controller kt feeder pillar dia
mcm Schneider punya ni...LINK

Tp, kalo MCB/MCCB indoor tu trip pasti ada fault.
Kalo xda, ELCB/RCD yg trip...

Yg satu utk appliance dan wiring faults
satu lg utk earthing dgn incoming supply faults

Bole?
