If your lights go out, or an electrical appliance suddenly stops, it’s probably because an MCB (miniature circuit board) has tripped on your consumer unit. This is usually caused by a lightbulb blowing, or a faulty appliance causing a short circuit.
Don’t be tempted to just switch the MCB back on. Replace the bulb or disconnect the appliance you think might be the cause before resetting the MCB. If it trips again, unplug other items on the circuit until you find the fault.
