I've been shocked by European 220V few times.
It is pretty itchy, especially in humid weather.
In CA I had couple of situations, when standing on plastic bucket I was connecting outside light. With 3-way switches you are never sure if the light is on or off, but I always tap the wires before touching them.
So tap gave me no shock, allowing me to twist the first wires with my bare fingers and putting wire nut on it.
Than I put other wires together and the light come ON !!!
Standing on plastic bucket on dry ground I was like bird on a wire.
Anyway. New building codes made my putting AFCI in my new house.
Over the time I had them popping up. One turned out to act to my laptop charger.
The other would break with central vacuum.
So in the end I replaced $50 AFCI breakers with $4 traditional ones.
