Identifying hot and neutral conductors, and detecting the presence of AC voltage at outlets, switches, circuit breakers, fuses, and wires and cables, detect 50-1000 AC voltage. Measurement category: category 1V, 1000V per UL 61010, to find a break in a hot conductor, the wire breakage point is where the signal stops. To find a break in a zero line, it needs connecting a load between the hot conductor and zero line, the wire breakage point is where the signal stops.
