no offence to the OP, but I don't think we should be encouraging guys who can't wire a light circuit to find a cable that is live..
it's on a similar par to the electricians secrets like "touch it to see if it's live" or my favourite " short it out and see which one blows " to find which breaker a circuit is off..
