Voltage detectors are a quick, inexpensive way to check for the presence of live voltage on ac circuits, switches and outlets before working on them. Also known as voltage wands, sticks, “power sniffers” or pens, they clip into a shirt pocket and “chirp” or glow when they detect voltage on exposed conducting parts or through insulation. These types of voltage detectors are designed for non-contact, live-not live voltage detection on electrical circuits found in residential, commercial and industrial buildings. Incidental contact with live electrical conductors is not an issue as long as the detector is rated appropriately for the voltage level and the electrical safety category in which it will be used. In addition, the user must exercise safe work practices and wear any appropriate PPE required.
