Advice on appliance testing
To carry out an appliance check, you should disconnect all appliances throughout the property.
Once this has been done, the consumer unit (your 'fusebox' or 'circuit breaker') can be checked again – return all switches to the on position.
One by one, plug in and turn on each appliance.
If the electric trips again, it’s likely to be the last appliance that you plugged in or the socket itself. Another appliance should be checked in this socket and if it doesn’t trip, it was the previous appliance that is faulty.
