why are there separate neutral and ground wires for electricity when they both are connected to the same thing.
In: 215
If the frame of the appliance isn’t grounded, a bare wire can shock you.
Connecting the neutral to the frame will protect you from that, while introducing a different problem. If there is a break in the neutral cord or wall wiring, then the frame will also have high voltage and shock you.
With a neutral, and a separate ground, bonded to the frame, it will take two independent faults to shock you.
