He (Dave P.) is right. Once you're about the amount of current sufficient to be lethal (which is measured in milliamps, not amperes), the ampacity of a circuit you're touching--whether 15, 20 or 200 amps--matters not. No reason to be overly impressed by a 60-amp circuit. No more deadly than a 1-amp circuit. -- I am a Canadian who was born and raised in The Netherlands.
