Hot Stick: Tester

Top Definition

This is a safety device used to determine if an AC voltage exists in a powerline. Fire departments use them to identify dangerous downed wires and linesmen use them to identify live or dead cables. The units vary but have either a light or an audible sound or both which gets louder and/or brighter as the voltage gets higher.
