OK - B32 MCB and B16 RCBO.
Without commenting on its correctness (in terms of what happened) I suspect that is what many/most of us would have guessed as the most likely (if we were told that more than one device operated) - certainly me.The plot thickens.... OK - B32 MCB and B16 RCBO.

As many as it takes - but don't expect me to necessarily indicate immediately if/when someone gives a correct answer!how many goes are we allowed
Right, we've had votes for most of the protective devices - so this is where I make it a bit harder for you all ... we are not looking for a single answer - more than one device operated!!
I see what you did thereSo, which one(s) of that selection of protective devices do you think/guess had operated as a result of the fault?

If you like thickening plots, I would add that there is also a slight 'intellectual twist' to the question as well!

Any theories as to why you think the RCD may have operated? As I indicated, there was no 'earth contact' - in fact, the cable was cut 'in mid air', and the 'live' cut end fell onto a (dry) paved patio.I'll stick to my guns and say, 32A and RCD at CU.
NopeDoes '... class 2 ... ...no contact with earth...' have some perverse significance, I wonder...

That's a good point.I know of some RCD protected socket outlets trip when power is cut, so now leaning toward 32A and RCD at outlet.
OK, I'll give in slightly and award some sort of prize to EFLI (and PBoD), since this was the additional 'slight intellectual twist' to which I referred. The (active) RCD socket did operate, but I presume as a secondary consequence of operation of an upstream device (there's one clue for you all!).That's a good point. If so and it is an active RCD socket that means the power to it was cut so I'll now say this RCD socket and the 16A RCBO.I know of some RCD protected socket outlets trip when power is cut, so now leaning toward 32A and RCD at outlet.
no theories, just irrational thoughts and aimless stabs in the dark at that moment.Any theories as to why you think the RCD may have operated? As I indicated, there was no 'earth contact' - in fact, the cable was cut 'in mid air', and the 'live' cut end fell onto a (dry) paved patio.
