True - and I suppose Harry's post: .... is a valid argument in this situation.
That makes at least three of us,then,but I'm slightly surprised that you accespt that view,given that it's not much different from youyr comment to me
"I know you think some advice to such people is better than them doing it anyway without advice but where is the limit?" -which I thought was something you didn't really like?
However, you sometimes ask if the millions of pounds spent on RCDs has been cost effective and have RCDs ever saved anyone, so perhaps someone might ask if Veedee fitting these two RCDs was worth doing at all. Is the risk of doing the work greater than that posed by not having RCDs on the lighting circuits?
It's not millions, it's billions. However, for better or for worse, 'we' have decided that we want ('need') RCD protection,and that 'advance'is never going to be reversed -so that question which I often ask is essentially moot.
As for my question, I would think that RCDs are inevitably
not 'cost-effective' (in comparison with other uses of money) since there was never much scope for them to 'save many lives', given that there were so relatively few domestic electrocutions in the UK (a good proportion of of which no device could prevent) even before we had RCDs. In contrast, if those billions were 'redirected' (e.g. to road safety,health care,medical research etc.) there would have the potential to save prevent far more deaths/suffering.
... but, as above, the notion that we 'need' RCDs is certainly not going away,and we now have at least a couple more levels of 'new fangled devices'which we might also 'need'...so where is the end to all this? I'm not sure that 'Nanny'is too much to blame for this. Each 'advance' happens when something becomes technologically possible (to mass produce),whereupon those who decide to manufacture them have to convince the world that the new-fangled device is 'needed' - and, unfortunately, 'rregulators' seem only too quick to jump onto ('be taken in by'?) such band waggons !¬
