Where else do you think the leakage current goes? How often does a person connect themselves to another circuit's neutral while taking a shock? Even then the current still goes to earth.

Johnny B Good expressed precisely :
I didn't suffer any burns - how serious a belt you receive, depends upon the conductivity of your skin, its resistance. Unless I am very hot and sweaty, I can touch across 240v with a barely noticeable tingle. I have tripped RCD's without even noticing I have tripped them.
Johnny B Good brought next idea :
A guy I was working with once, suffered burns on his arms. He was working from a ladder alongside a 3Ph works crane, the crane was of the style used back then and ran the full length of a bay, using a catenary bare copper along the full length of the track, with pickups on the mobile crane. He had failed to isolate the crane, the ladder had slipped a bit and had grabbed the bare live lines. He was lucky he could let go and climb down, but you should have the howl.
Yes, they effectively trip on earth leakage whilst not directly measuring it. Quite clever really.
A pendulous enlargement? I think the yanks call that a "semi".
No, fricking hurt and made mental note not to do it again, not that it's prevented me getting several other belts from the mains.
Pendant.
It's a while ago but ISTR having a painful arm for an hour or two after so despite being on top of a wooden chest of drawers some current did flow through me not just across my finger tip.
I think you under estimate how easyly 230 V can shove 30 mA down the multiple parallel paths that bypass the second winding in an RCD.
Damn those low hanging pendants! Presumably you were stretching out to reach the pendant so I guess you disconnected yourself quick smart when you completed the circuit, neatly limiting the experience to no more than a nasty jolt. That's not to belittle the experience but it does highlight why, other than for obvious misuse cases, BC and ES lampholders remain largely unchanged in design over the past century (and virtually unchanged over the past 6 or 7 decades at least).
It never does. It just makes you wary enough of lamp sockets/holders to treat them with a little more respect. :-)
Makes you wonder how you managed to bridge yourself to earth or a connection to a neutral via some other part of your body.
I don't underestimate the possible sources of earth leakage paths (8K ohms or less required btw), I was just completely discounting them in this particular scenario where the hapless victim has managed to isolate themselves from contact with any such earth leakage paths. This a common enough scenario in a typical home environment when changing a pendant lamp these days such that the hapless victim can receive a nasty jolt without fear of tripping an RCD or ELCB or electrocution.
We use 240V and many European countries use 220V. 230V with a wide enough tolerance means that products designed for "230V" can be sold both here and on the continent, without having to have separate products for each voltage.
