[QUOTE="Doc Hudson, post: 453517, member: 1607"] Proving the continuity of the loops is nothing to do with identifying the cause of RCCB tripping, you need to test the insulation resistance between L-E, N-E. And you probably need to verify the trip times and sensitivity of the RCCB. Testing loop continuity for this fault is like checking the washer bottle of your car to see if the tyre treads are worn. It is a valid test, but the wrong test for your symptoms. i.e. breaking open a ring circuit would not cause an RCD to tip. Doc H. [/QUOTE]
