[sdiy] Neutral ground [was: midi optocouplers]

[Bob Devries]

In Australia, which uses 240V 50 Hz, and a 3-wire mains connection, neutral and earth are connected together at the entry point to the building, usually the meter box.

  So does this mean that neutral and earth ground are the same? Or am I missing something? It's been a long time since I studied this in school.

    Hot will have 120V AC with respect to earth ground

    Neutral should have no voltage with respect to earth ground.

    They can get reversed sometimes... with disasterous results in
    an audio system.  Having one chassis at 'hot' and another at 
    neutral can mean line voltage in an audio cable...
