Where the voltage is very low, the bared ends of the conductors constituting the two sides of the circuit are held a short distance apart on the tongue. The method is feasible only where the pressure is but a few volts and hence is used only in bell and signal work. The presence of low voltages can be determined by tasting. Use the method with caution and be certain that the voltage of the circuit does not exceed 250 before touching the conductors.ġ59. Which are the outside wires and which is the neutral wire of a 115/230 volt three wire system can be determined in this way by noting the intensity of the shock that results by touching different pairs of wires with the fingers. Therefore, the method is not feasible in some cases. ![]() Some men can endure the electric shock that results without discomfort whereas others cannot. This method is safe where the voltage does not exceed 250 and is often very convenient for locating a blown-out fuse or for ascertaining whether or not a circuit is alive.
