[QUOTE="Doc Hudson, post: 461478, member: 1607"] Not very bizarre and I doubt you have saved anything, merely postponed finding the true cause that a DIY person who has no access to test equipment, such as an Insulation resistance tester, cannot diagnose via forums or you tube. I (and I guess the majority of qualified electricians on here), have seen numerous instances of intermittent problems on various types of circuit that an unskilled person had previous diagnosed as cured because it had started working fine again for a few weeks. I would be cautious of leaving any circuit that has tripped a 32a MCB for very long without having the standard dead tests carried out to verify the cable integrity. There are a lot of dangers with your current diagnosis approach, rather like choosing to drive a car with bald tyres, it could work fine for a long period, but should you need to stop quickly it could be fatal.
