Too Modest

If it can be demonstrated to the scientific community/press/public at large that "the RCD will trip or nary a tingle will be felt", then CBE's, MBE's, Knighthoods or perhaps a Nobel prize will be sure to follow!


This is surely the biggest step forward in Electrical safety since the invention of fuse wire!


In these bleak times the British public needs to hear good news like this.

    I think you’ll find it’s a lot bloody quicker than that!  Try the speed of light and you will be closer.

    I get the feeling there is a big gap in your knowledge of electricity.


    Of course there are gaps in my knowledge, nobody knows it all.

    I was told to just make sure that I understand my bit, which I do thank you very much!


    Therefore I refer you to the original post:

    Demonstrate to the world that that graph is correct at the relevant supply voltage (of 230v) and collect your Nobel Prize for making the biggest contribution to electrical safety since the invention of fuse wire.

    Document IEC 60479-1 seems only interested in voltages ranging from 25v - 200v.

    It would appear therefore that in order to produce that graph, the authors have been increasing the 'touch' voltage in order to increase the current flow through the human body.

    Therefore that graph is a misrepresentation!

    It is also misleading in the extreme and dangerous to the point of being potentially lethal for the purposes of "Requirements for Electrical installations".

    Simple, more current flows, as I said, it’s Ohms law.


    More current flows faster!

    Hang on a minute. If you increase the voltage and the resistance stays the same, less current is going to flow.




    What?




    I = V/R


    For a constant resistance, increasing the voltage increases the current.

    Yeah apology's, needed to do a bit of deleting and editing there.

    As usual with electricity, the answer was more simple/logical than it first appeared!
