originally in the 16th. RCD protection for sockets likely to be used outdoors. 1991.
later amendments to 16th stipulated RCD protection for sockets for general use. can't remember exactly when. mid to late 90's? then on the issue of 17th , RCDs were stipulated for the benefit of kitchen fitters, picture hangers, and general Destroy it Yourself merchants. ( cables buried in walls )
Hopefully what ever is in contact with the nail can pass 30ma. If its just wood Id think no trip.
Early 80's (15th edition) This was for socket outlets that were specifically intended to supply equipment outdoors and I presume came about with the intention of reducing the number of fatalities when people were simply trimming their hedges and mowing their lawns.When were RCDs mandated in the regs?

You'd be right. But the moment a person touched the nail, then 30mA might pass through them and be very quickly turned off.
Without the RCD a few amps would have to flow (by which time they'd be dead).
Of course, nothing at all to stop that person thinking, "Huh!" and resetting the RCD again.
Damaged cords usually caused by the appliance in use and then the unsuspecting operator coming into contact with the exposed live core.What was behind those fatalities? Damaged cords or missing CPC?
and while you're at it, fabricate a non-combustible, i.e. ferrous metal cabinet for your chip pan. according to statistics, 50 x more house fires are caused by chip pans igniting than by plastic CUs.It's funny, I have owned a house for 29 years but never had an RCD
My current house does have MCBs but sadly no RCD!
Perhaps I should upgrade my CU to a nice shiney metal one
