I see that in Europe, a GFCI is known as a RCBO (residual-current circuit breaker with overload protection) . You guys sure have a different way of wiring a house. Ring Circuits (ring mains) used to be used in the high voltage neighborhood distribution system but we never used rings inside the house.

Contrary to Minimac's idea, I don't think many people want to test out what it feels like to get shocked. I got it once across the chest and hope to never feel that again.

I hope Minimac never tries to find out what it feels like.
