Power goes in at HOT, goes out at NEUTRAL. It can also go out on GROUND, but if that happens, something is broken (since GROUND is supposed to be connected to the outside of your device, and cou only want your power inside the devoce, not at the outside). There are devices in the junction box that see if power goes out at GROUND (which it is not supposed to) and emergency-turn off HOT to save you from getting shocked.
