Hello forum , good day to all
Accepting it can be a bit more involved science wise, but will any of you please share [if you use/have] a general/simple ‘formula’ or 'rule of thumb' for working out how many LED lamps that a MCB/RCBO Type B or C of some rating is able to switch and not end up nuisance tripping on same-time startup ?

What about employing startup-current suppression (local to light unit or otherwise) … what ready form might that take and what are the implications ?
Interesting comments on some approaches. It would seem sensible, as touched upon above, to liaise and stick to a manufacturer using their confirmed properties.
Still, in trying to get an understanding (if that is possible), I always find making up an example useful, so (using same as for some of the surge questions that have been on my mind):-
same-time startup one circuit of 600 - 900 w of LED lamps over a ~100m run
Based on one's experience and/or expert or rule of thumb knowledge, is it likely that a type C MCB/RCBO e.g. of 10 or 16 amps would hold up ?
It may be the case that consulting the lamp manufacturer and then passing on to the protective device manufacturer to see what's likely is the only sure way, without some standardisation etc.

just to add … i came across this helpful piece for an insight !
