Current Sniffer

Top Definition

These devices detect the presence of voltage without direct contact with the wire. One style (Greenlee 1010 or Fluke 1ACA1) looks like a pen and you touch the tip to a possible power source such as a wire or outlet and if the tip glows red, you know there is some level of voltage present. An upgraded version of the Greenlee 1010 Volt Tick called the 1112 includes a flashlight. The other style is an audible detector that chirps as you get closer to the load, detects a higher and lower voltage range, detects both hot & neutral, and detects if breakers are powered.
