Today a light bulb went off from the ceiling lamp. Instead of normal peaceful passing out this particular light bulb decided to explode violently. In addition of causing nasty mess in sense of shattered glass it also tripped a switch from the circuit table.

Strangely, after digging out the remains of past light bulb and replacing it with the new one lights did not work. And there was no electricity in the toilet. Even the oven was cold despite well working cooker just above it.

After some playing with the circuit table's switches without any success I decided to go downstairs to check if the building's electric main room with all those electric meters would provide any clues. Well, there was a red light on the meter of this flat. This flat has three mains coming from basement and each one has its own trip switch. The nasty light bulb managed to trip also one of the main switches off as its last deed.
