Ideal Industries TL-82 Resistor-Fused Test Leads for Voltage Tester

Voltage testers detect electrical current in cables, cords, circuit breakers, switches, wiring, and other components of electrical systems. They can test for live circuits, proper grounding, adequate voltage, and flowing current. They might be used by homeowners to test electrical outlets or by linemen to test power lines. Available in a variety of styles and levels of sophistication, some models simply indicate the presence of electrical current, while others record or display the level of voltage conducted. Some have additional capability such as the ability to perform continuity tests.
