If your only points of contact are Live and Neutral then no current flows to earth. A dry carpet does not provide any path to earth.
No matter how much protection is provided shocks are still possible. The current and duration may be limited by protective devices but even with those limits ( 30 mA and circa 40 mSecs ) the shock can be fatal depending on the points of contact with the body. Or the shock can create a muscle action that results in a fall with subsequent injury.
I wasn't recommending it.
Merely pointing out that a CPC is not necessary for the operation of an RCD.
As I said, levitating.
Or on insulated ladder or rubber mat.
Who said it was a dry carpet.
So, in normal day to day living -
when only a live line conductor is touched does a person feel anything and does an RCD operate?

Arrrgh, don't you start we have enough trouble with Mr (?) Cockburn
I will never forget a mate at school telling me how he had once got a shock. We must have been about 10 years old when he told me. Table light (or some other appliance) didn't work but he had seen his dad change a fuse in the plug before. So he unscrews the plug, changes the fuse and decides to try it before screwing the plug back together. Pushes plug in socket, live and neutral pins don't go in with the plug. So left thumb on left pin, right thumb on the other, and push.
Even if they had RCD's in those days he still would have had a shock. Presumably his hands shook free as he was fine afterwards.
SWMBO also told me once about a butter knife which was never the same again after her brother used it to lever out a stuck plug when he was too young to know better.
Do I take it you think the answer to both is 'no'?
Yes, indeed - sorry 'bout that.No it won't. It will limit the time for which a current above a threshold level (e.g. 30 mA) can flow.
Possibly. Possibly not.

Quite true, I was not making a distinction between CPC and earth.
All things being equal then some current should flow to earth, however, to use the original scenario, one does not need to levitate to end up with no path to earth.
Imagine leaning into the back of a domestic washing machine. It is hard to reach and so one wriggles over the top a little. Feet no longer touching ground and lots of clothing between lip of machine and body. We must all have done something similar at sometime. Arm down : elbow touches neutral no problem until finger tip touches live. No current through heart, or rest of body, but forearm cooked.
It you are TT and PMSL then go green and water saving and wet the earth rod, while standing on a dry carpet in case the the CPC isn't at ground potential until the rod has been wetted.
I knew I piddled in the garden for some reason!!.....and wet the earth rod.....
Oh yes, just remembered! 2 females in the house, no bathroom access!
Move away from that patch of carpet NOW.Shouldn't laff but PMSL here!!
Do it on the compost heap - it's good for it.I knew I piddled in the garden for some reason!!
Build some kind of platform over the compost heap, with steps up to it, so that they can help it along too.
