Re: Lamp limiter plus Variac tip
Thanks for doing the experiment, Al, that's above and beyond the call of duty right enough!
When I was a lad, I used to be able to feel a noticeable tingle from the half-wave-rectified '12 volts' from my model railway transformer. It seems that we become physically aware of currents well below levels at which they become potentially harmful.
The 300ms tripping time allows up to 20 cycles to pass, barely enough time for you to utter the first "o" of "ouch!" before the RCD cuts off the supply. You'll survive, but it may hurt for a while.
