Albert said:when an RCBO trips, is there a simple way to find whether it was a current leakage or overload, or we have to run a comprehensive test?

plugwash said:the old mk 2 module rcbos did this (not that they are avilible anymore) and i'm sure i've seen other makes of 2 module rcbo with the leaver split into 2 parts to indicate how it should trip
I don't know wether you read the messages above, the original question was about a simple way of identify the cause for a RCBO to trip, it could be overload current and/or current leake, without the need to disconnect and check the wires. the idea of using a clampmeter, is to put it around the wire coming to/from the RCBO and turn the RCBO on, a high current will indicate overload a low current will indicate current leakage. can this work if not could you explain whyBR said:perhaps, if you had a meter with 'inrush' capability. but i fail to see the purpose. A megger or even continuity test will show up a 'current leakage'
