You know that having a ground is as simple as burrying 10ft of copper pipe into ground ?
Regardless - most devices don't need ground other than for safety purposes in case of a fault. All are made to work without.
However, not having ground is stupid.
If you are worried, unplug before use (water heaters etc) and you are safe.
Breakers are designed to trip at specified current.
10A breakers trip at 200A.
All it takes to kill you is 50mA.
You need an RCD to provide safety.
However, they won't provide no-shock experience
All they do is cut power in case of a shock or fault
You will still get shocked.
But you are less likely to die.
I don't think the diodes would take any significant amount of current flow after the dead short on the 5v side of the cable.
They take more than 10A before they burn out.
And they burn out in a way they go into short.
So, even more amps.
what would be a non-shit charger, you autist? It's all made in fucking china. 5v cannot penetrate the dielectric properties of even wet skin, and the path of current would have to pass across the heart or brain. story is horse shit.
It wasn't 5V that killed her.
It was insufficient isolation between primary and secondary. It arced thru and killed her.
Such events have happened before

Skin in this case isn't dielectric, it is resistive.
I meant to say is, 220 is actually deadlier. it uses a second hot lead that is in an inverted phase, making a peak difference of 220v. Basically a +110v line and a -110v line in the same circuit
It is. But 60hz is also deader than 50hz.
And peak of 220 is not 220, it is 300V.
You drop dead in water from 50V potential across your body.
