High amperage is also
more lethal than higher voltage at lower amperage. I think in the USA, our high tension pole lines in our neighborhoods carry about 44,000 volts. In countries with stabdard 230-240 volt service, is more efficient as the amerage draw can be less while providing the same amount of power per home. I don't recall off the t.o.m.h. what the line amperage is on either system, but their grids are more stressed than ours is. More people per square kilometer, and they utilized their electrfied railroads much more. water from the Alps provides hydro power in some areas. My dad knew a lot about electricity, and told me ome amp can kill if the curcunstance is optimal. Perhaps if one is standing in water, or on a solid ground.
