If an RCD trips i.e. switches to the ‘OFF’ position you can: Try resetting the RCD by toggling the RCD switch back to the ‘ON’ position.

How can I find out what caused my electrical trip?

An overloaded circuit will normally be the reason your circuit breaker keeps tripping. The culprit is usually the combination of lights and appliances you have on the same circuit. It could also be a faulty appliance which is calling for more current than it usually requires.
