[QUOTE="SPECIAL LOCATION, post: 502518, member: 250"] Well, as most RCBO's don't actually switch the neutral, if one RCBO has tripped the 'N' is probably still connected..... So I am guessing it is something 'N' -> 'E' related..... What type of Earthing are we talking about? What if you had some sort of external fault coming up the earth & making its return via the Neutral..? One RCBO trips... but N still connected so another RCBO trips... etc... etc... etc.... Dunno.. just guessing?? :coffee [/QUOTE]
