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.

    Given that 30mA is enough to kill you, I think "nary a tingle" is wishful thinking.  The standard European 30mA RCD is only intended to be quick enough to break the power before you're dead.


     


    How is a standard European 30mA RCD intended to be quick enough to break the power before you're dead?




    By tripping in a maximum of 300ms at 30mA, and quicker if the current is higher.


    The biggest worry with electrocution is the heart.  But the clever thing about the heart is that it will automatically restart itself after a brief zap.  That's how hospital defibrillators work - they are rebooting the heart.  So long as the heart hasn't suffered from any permanent damage, you should survive.
