We are trialing a new camera system and associated components that is wired through an isolating transformer.It is since we began to use this equipment that our problems started. Unfortunately the system does not immediately trip when plugging the camera system into the mains supply, but this is the only common piece of equipment being used when the problem occurs.
All leakage tests on the camera system have given the expected results. It could be that the monitoring system is faulty and I am awaiting for this to be tested.
