Part of the power plugs in my flat stopped working this morning. I checked the breakers box and one of the breakers was in OFF position, with a yellow indicator.
After checking the producer's website, I've come to the conclusion that this means fault current. Here is the exact model:
I've disconnected all appliances from the power plugs and tried to reset the breaker, but it returns to the OFF position with the same yellow indicator.
My electrical engineering skills basically resume to those needed to change a light bulb, but I would like to understand if there is something I could check or do in this situation before calling a qualified electrician.
I'm also interested in a (layman's terms) explanation why the breaker is indicating fault current when there are no appliances connected.
