No wonder people get confused......

I'd suggest after reading this that no one had better use the mains socket switch to turn their kettle off.....

Take a look at this

While it's not a bad explaination of how it works does not mention they need testing periodically

Electricity + magnetism = electromagnetism

The point I was alluding to in that explanation is that the author of it completely missed the point of how it works. He seems to think that if you cut the live wire the RCD will trip. Obviously every time you throw a switch off you are cutting the live wire. That's why I mentioned not making a cuppa if you have one of his RCD's protecting the kettle.
The whole point of an RCD is earth leakage detection. He failed to mention anything about that and as such renders explanation inaccurate.
Disinformation is really worse than no information because it can very easily lead to unsafe working practices by people working in good faith.
His basic idea of how it is wired is correct, but his theory is plain wrong. Where he mentions cutting the live wire he should have inserted connecting the live wire to earth by various means including some poor soul touching the live whilst they are earthed or a fault causing an earth leakage or maybe just cutting the cable and the blade making that connection. It doesn't matter which way it is done, but done it has to be.

Very good point, I thought I had the wrong link. I live in Norwich, we don't get out much.

I prefer electricity + kettle = cup of tea.

I prefer electricity + kettle = cup of tea.

Ha ha...yes indeed and with that I think I'll see if I can get 'er indoors to make me one.....

missed his theory, fell asleep after reading the first 4 lines
