Hi All,
I hope I am using the right terms here, I have a situation where my consumer unit is 15 way, and I believe MCB are the breakers which trip when there is a fault with a specific circuit, and RCB is the main big one which controls either half of the CU or a group of MCB’s.
Now, if my assumption above is correct, what I am experiencing at the moment is situation whereby one of the RCB’s trip, but no specific MCB trips, so I don’t know what circuit is faulty and causing the RCB to trip. Whenever this happens, half of the house has no electricity and once I pull the RCB back up, everything works ag again, then randomly in the space of 1-2 weeks the same thing happens again, there is no definitive pattern, something just makes the RCB trip.
The RCB which trips is the one that is circled in the picture, and everything to the right of it stops working until I pull it back up again.
