20 Must-Have Tools for Electricians and Service Technicians

14. Circuit Finders

Circuit finders typically consist of two main components: a handheld digital transmitter and small receivers that can be plugged into outlets around the home. The transmitter sends a signal through the electrical wiring, and the receivers detect and indicate which circuit the specific outlet or wiring belongs to.

This eliminates the need for trial and error or physically tracing the wiring, saving valuable time and effort for the electrician. By employing circuit finders, electricians can swiftly and precisely determine the circuit connections, streamlining the troubleshooting process and facilitating efficient repairs.
