We have been doing work in a flat where we had taken down light and put a temp ceiling rose. All was fine for a month then we fitted new expensive chandeliers. Worked fine for a few weeks then on some mornings the circuit would trip with a bang. Went back did a ir test all was clear 10m ohms between n-e l-e. Tested light that it was blowing from all was clear. Left off for a few days no problem. Refitted it and after a week it starts happening again. Light supplier says it carnt be the light as it would not cause a short. Any thoughts it run in singles in conduit.
