How to find fault on a ring final circuit sometime called a ring circuit or ring main. Using a Megger MFT tester Marcus sets about finding an open circuit after carrying out stage one testing end to ends. Marcus show you how to split the ring circuit into 2 radial circuits and then test each leg until you find the faulty socket is identified.
Please note there are many different ways to find this type of fault...
