I always hear it is the current aswell, and if we go by formulas of voltage and amperage relation, the lower the voltage, the higher the amperage, right?
Shockingly surprising it would be to find out that my household plug is more dangerous than the 220V one (for the air conditioner and showers).
Anyways, i bet theres some energy limiter before the energy comes to the house.
Voltage / Resistance = Amperage.
The danger for the body is the amperage, exposure time and where the current goes through the body. Does the current go through the heart, a really small current can be deadly. Only going through an arm or leg, a high current with long exposure time can burn the flesh and poison the blood that way.
Electric fences have voltages of 1000V - 10.000V but only short low current shocks. That way they are not dangerous but hurt a lot.
The resistance of the human body can vary a lot from person to person or thick rubber shoes can insulate to the ground. In germany, voltages below 60V AC or 110V DC are considered as protection low voltage, not dangerous anymore in most cases (AC more dangerous since varing voltage does effect the heart more).
Another good thing to know, fuses do not protect you against shocks, they protect against short circuits melting wires and starting a fire. To protect against shocks, residual-current devices (RCD) are needed. Good ones react agains faults less then 30 mA in less then 0.2 sec. And even then touching is dangerous.
220 VAC won't kill healthy normal adult. Even 380V AC. I tried this once (accidentally).
Actually a 380V is made of 3 220V cables that run out of phase. So touching only one wire shocks you with 220V. Only touching 2 wires at the same time shocks with 380V.
