you can see lightning...
My moons ago when I was an apprentice, we were going to replace a 3 phase motor contactor. We isolated via the Klöckner-Moeller isolator, however it as we (my mentor) started to disconnect the contactor there was a sudden outburst of expletives! It would appear the isolator was indeed faulty too and also had to be replaced. We had to trundle all the way back to the DB age pull the fuses. Lesson learnt was always check for disconnection.So, why did the RCD not trip the power? How did you feel after the initial shock? No pun intended but I did feel energised after a 440V shock.
True. My brother was working on a deck crane and isolated the supply. but it had two supplies and he got a nasty shock. It's quite common for electrical machines to have two supplies, especially on ships. If both supplies are not isolated one switchboard with its own supply properly isolated, can be back-fed from the other switchboard. Modern systems normally have keyed interlocks to guard against this. Good, written switching plans are essential. I worked on 11kV so had to know the systems on board.
Yes you have :) Remember the Van der Graaff generator at school? Easily 100kV right there. Rub your jumper with a balloon- 10 or 20kV.I’ve never had an 11Kv shock

It's the current that kills you.
The right breaker in the household box did flip, but it's quite an old unit and not one of these super flashy modern things and it let me know about my mistake before tripping out.So, why did the RCD not trip the power?

I suggest you try 440v first. Don't run before you can walk.I’ve never had an 11Kv shock but I imagine that would hurt even more than 240v (or maybe not at all!).
Please get a modern unit or at least an RCD/RCCB it can save your life.The right breaker in the household box did flip, but it's quite an old unit and not one of these super flashy modern things and it let me know about my mistake before tripping out.

I don't think anyone survives contact with more than 1,000 volts.
Looks like we are all electrically incompetentBut what's your voltage?! I've only had ten people vote!
