    If Voltage of AC is above 50V, it will break your skin and then the current and time kills you.

    Multiple grounds? There’s only one ground. You’re walking on it.

    120V/240V, Split-Phase – Center-tapped

    120V AC – 1-Φ = Any One Hot (L1 or L2) + Neutral Wire + Ground Wire
    

    120V/208V, 3-Phase – Wye

    120V – 1-Φ = One Hot + One Neutral and Ground wire.
    

    120V / 208V & 240V, High Leg – Delta

    120V – 1-Φ = One Hot + One Neutral and Ground wire.

      Neutral and Ground are bonded at the first point of disconnect, which provides two paths to ground in the event a ground is lost was my point. Not that there are somehow “two Earth’s”.

        It’s the same with 3 Phases, as seen in the source I provided.

        Neutral doesn’t work as an extra safety line, because it’s connected to neutral in the device, not to ground.

        Maybe dont make ridiculous claims when you don’t know what youre talking about. I hope you arent an electrician.
