At the entrance you will find a black button. This general power switch must always be left on!
Be careful Private electric voltage in Italy supports a maximum of 6KW. This means that if you turn on the air conditioning, washing machine and electric water heater, all at the same time, the fuse will blow.
Power outage If a fuse blows you have to check in two places to get electricity again. In your apartment there is a small electricity panel at the entrance. To get the electricity the switches should be all up. If any of the switches is down, turn it up. This should solve the problem. However, if you still do not have electricity you have to turn on the main fuse. This is not located inside your apartment. You will find it beside downstairs next to the gate inside the wooden cabinet. Yours is the number 5 and you only need to pull it up again.
