1. Get an electrician to test and trace wiring to identify locate and isolate the fault. 2. If there are still unidentified cables - get the electrician to test and trace to identify. 3. Once the fault that is tripping circuit is identified, can assess what is required to repair, for example new fan required, or new cable required between fan and isolator etc. If it is a cable fault that is concealed within the fabric of the building then sometimes you just have to trust your testing and rewire without ever specifically seeing the faulty piece of cable. I would estimate up to 3 hours work to diagnose but likely less.
