It's the modern equivalent of a fuse box. Instead of old, removable style fuses it has miniature circuit breakers which are switches that can be easily reset rather than replaced as in the case of a fuse. If there is a power surge, faulty wiring, or a fault with an electrical appliance, the miniature circuit breaker for that electrical circuit will trip, breaking the circuit and cutting off the power for that section of electrics. Step 1: locate the MCB unit. If the lights have gone down, you may need a torch. Your MCB unit is usually near your electricity meter. They are often higher than is easily reachable. If this is so, carefully set up a ladder. Step 2: reset. Each switch in an MCB unit relates to a certain section of the electrics. If one of the switches is pointing in a different direction to all of the others, push it back up to restore power to that circuit. Done.
