Extech Wire Tracers

Wire tracers and Circuit Breaker Tracers come in many varieties. The most basic wire tracers cost less than $40; the “toner” tool injects a traceable signal into a wire, which is picked up by the “tracer” tool. These basic tracers can also perform continuity tests.

Basic Wire Tracers

Basic wire tracers are simple, relatively inexpensive tools. They are designed to trace a wire using an injected traceable signal. The drawback to basic tracers is that they require that at least one terminal end of a cable be exposed for the wire to be traced. This is because the traceable tone can only be injected via direct contact. More advanced wire tracers do not need any exposed terminations to trace wires because many can inject a traceable signal via induction.

More advanced wire tracers can trace

• Energized, de-energized and open (broken) wires behind walls
• Locate and trace wires underground
• Locate breakers

Many advanced tracers also feature

• Adjustable sensitivity modes
• Clamp-on attachments that can inject a traceable signal without contact via induction

Circuit Identifiers

Circuit identifiers make it quick and easy to locate and verify the presence of power. They are used by professionals to locate, verify, and troubleshoot circuits. There are two main types: analog and digital. Modern versions are extremely accurate and easy to use.

Circuit Identifier Applications

• Breaker and fuse identification
• Verify presence of power
• Troubleshooting
• Locate AC circuits
• Verify proper wiring
• Trace wires behind walls

Key Features of Circuit Identifiers to Consider

• Automatically indicates the right breaker for quick & easy breaker identification
• Non-contact voltage sensor included
• Includes GFCI receptacle tester
• Can be used on de-energized/energized circuits
