Bogger -
Well... I guess that would be true if you were hanging onto those bare wires 100% of the time the circuit was locked out. Many times, during my current apprenticeship for example, I am moving a ladder from junction to junction, along with other duties while I'm working the circuit. Plenty of "Non-contact time" to possibly let me know before I open that next box. I am surprized that no-one has built such a simple device yet... Thanks for the response. J.-
