Heh, yeah since in europe you run 240/480 volt systems there is no neutral ...but also losing the ground to the grounding grid of your home basically makes anything with current in it use you as the quickest route to ground since it has no where else to go....
Also US national electric code requires all homes to have 2 8' ground rods (galvanized or copper clad) driven 6' apart from each other along with a cold water bond if you do not have PVC plumbing. As for 2 wire 120v systems they went out in the 70's with the introduction of the GFCI (Ground Fault Circuit Interrupter). Basically kills the circuit within milliseconds of a direct ground fault between hot to ground or neutral to ground. Most commonly found in the bathrooms and kitchens and for outside receptacles of home below 6'. A new addition to this that will save alot PC users from ground fault issues in new homes is the AFCI (Arc Fault Circuit Interrupter) which is now required in every bedroom of a new home. I know I don't know everything about electricity but after 13yrs in the trade I've seen quite a bit and seen alot of changes to how we do things. I also don't know what powers that govern the codes of european countries but I'm sure things are very different with the different voltages you use. That said the basic principles of electricity still apply, you grab a wire that's hot or under load and it is gonna use YOU as its quickest route to the earth lol
BTW it hurts like HE double hockey sticks!!!!!!
I get nailed on average of about 3 times a week lol Slippery fingers lol Also couldn't even give you an estimate of how many tools I have practiced AC arc welding with
