You're asking the wrong person, but I suppose that is what some people think/believe. Personally, I would lose no sleep whatsoever if I had, say, '6A rated' switches roses, pendants or whatever in a 16A lighting circuit.I suppose it is. So is it the switches and lampholders which may be damaged by this current even if the cable would not?
Advantageous to whom, and for what reason? - so one didn't have to install an OPD or use fatter cable? As you know, I'm on your side as regards omission of overload protection in many circumstances, when fault protection is adequate (which, as I've just written to eric, it virtually always will be), but I'm not sure that I could claim that it offered any tangible 'advantages' (other than saving a little time, cost and maybe a bit of copper - none of which would be of much concern/interest to the regs!).Well - if you like but if it complies with the omission of overload regulations it could also be considered advantageous.I think one might struggle to come with reasons which sounded particularly 'advantageous', since it's generally a matter of convenience/laziness/cost (i.e. avoiding installing overload protection or fatter cable), mightn't one?
