He did not suggest, and I am sure would not have suggested, that 'no protection at all' was needed.

I have edited since that quoted text. Sorry I was retuning the TV and trying to post..
Fair enough, but even after your edit you still write ...
... i.e. you still persist in adding that "at all", which EFLI was not saying or implying. He was saying that overload protection was 'probably not needed', but I'm sure he acknowledges that fault protection is needed (indeed, required as a condition of omitting overload protection, per BS7671).
Kind REgards, John
It was in reply to this:
Incidentally, sockets are not rated for 32A.
Perhaps I should not have included 'probably'.

I'm not so sure, particularly given that Harry has thanked me for pointing out that the 'no protection at all' was his invention, not what you had previously written (which, unless I'm mistaken, was saying that overload protection would probably not be required, although {even though you did not say this explicitly} fault protection certainly would).
Kind Regards, John
Yes, of course. That's why I said overload - 433.
Indeed - but in your last post you seemed to be saying that Harry's comments were about something else you'd written, weren't you?
Kind Regards, John
Not sure I understand exactly -
although Harry said there was probably a 6A MCB (most unusual if not) so it does have overload and fault protection, but overload of less than 6A would not be required for a connector as one light cannot draw that much or, vice versa, that a connector block must be at least 6A .
I am not sure if connector blocks come in less than 5A anyway.

It's getting confusing! ...
... an uncleared fault current (i.e. if adequate fault protection were not in place) due to a fault in the vicinity of the light could be considerably more than 6A.
Indeed. In the dim and distant past, I recall ones called "2A", but I'm not convinced that they were any smaller than the ones now sold as "5A". However, as you imply, it's very many years since I last saw one described as less than 5A.

It could but that would not be overload - so has nothing to do with my original point.
Agreed - but as I said at the start of all this, back in post #14, it's almost a question of semantics - since the only sort of 'very high excessive current' a single lamp/bulb could bring about would be, to-all-intents-and purposes, a 'fault current' (i.e. due to a fault of {more-or-less} negligible impedance - such as an arc through plasma).
