A returning customer visit today. They have moved into a new house and were having issues with the electrics tripping. The fault was found to be incorrectly fitted outside lights and a faulty RCD (probably made faulty by the amount of times it had tripped due to the lights).
The armored cables were re-terminated with the correct external rated glads into new external boxes.
The RCD was replaced and tested for correct function as was the circuit for insulation resistance.
