I always thought AC current requires 2 wires to carry the current both ways just like DC. Recently I read a post on this sub saying neutral wires go to ground. What am I missing?

It might help to know that 120v electrical systems on Naval and commercial vessels work exactly the same as your home, but do not employ a neutral. This is for reliability. If any part of the system becomes grounded, it will still function. The grounded side becomes a sort of neutral conductor. This is known as an ungrounded electrical system. That doesn’t mean there isn’t a separately derived ground wire.
