    Dear All.

    I am working on AC Electric Circuits. I want to know that if we short Phase or Line with Neutral what will happen to the supply of 230VAC?

    Please help me with this.

    Regards,
    Sachin

    Are you talking about household wiring in the USA or someplace else?

    If you short Line to Neutral, the weakest link will be opened up. The weakest link is normally a circuit breaker or a fuse, if the electrician that wired it up was competent.

    If a component in the short circuit path had less of a current rating than the breaker or fuse, it will be fried.

    Note that causing a short of such high voltage, high power lines is to be avoided at all costs; such a short can result in an expanding plasma fireball of extremely high temperatures that will consume anything nearby - including people. :eek:

    I am not kidding.

    You will find out how well coordinated your circuit protection is. Depending on your protection and circuit capacity, you could experience a small spark and a thrown breaker, to line slap, arcflash and injury. You really want avoid this.

    Hello,

    Now you have seen some replies.
    I would say "don't try this at home".
