This tool is useful in identifying hot and neutral conductors, finding a break in a wire and detecting the presence of AC voltage at outlets, switches, circuit breakers, fuses and wires and cables.It has round cords that have twisted conductors that check hot conductors by sliding the unit along the cord. The voltage detector can be used to find a break in a wire to find a break in a hot conductor, trace the wire until the signal stops, find a break in a neutral conductor, and connect a load between the hot and neutral trace the wire until the signal stops.Features• Detect AC voltage in outlets, lighting fixtures, switches circuit breakers, wires and cables • Non-contact Shaft design • Locate wire break point • Detect 50 ~ 1000V AC voltage • Bright LED and sound alert if voltage detected • Detect live wire • LED and Tone Indicators Specifications• Voltage Range: 50 ~ 1000VAC • Frequency Range: 50 ~ 500 Hz • Measurement Category: Category 1V,1000V per UL 61010 • Temperature: 0°C to 40°C • Indoor use only • Battery: 2 x 1.5 volt AAA batteriesSet includes• 1 x Pen size Voltage Detector  • English User manual • Blister Packaging SKU: 284 Category: Cable Testers Brand: AZInstruments
