Functions
Breaker/fuse locate; receptacle wiring test (correct + 6 fault conditions); GFCI trip test
Fits locating breakers and checking receptacle wiring where you need an Extech CB10 with variable sensitivity, GFCI trip test, and indication of correct wiring plus six fault conditions.
Key advantages
- Locate — Finds 110–125 VAC breakers/fuses (90–120 V AC operating)
- Wiring test — Correct wiring + six fault conditions via red/green LEDs
- GFCI — GFCI trip test function
- Sensitivity — Variable adjustment to pinpoint the correct breaker
- Form — Snap-together receiver + line-powered transmitter; UL/CE
Typical applications
- Residential/commercial breaker identification.
- Receptacle wiring verification.
- GFCI functional checks.
Selection guide
- Voltage — 90–120 V AC / 47–63 Hz
- GFCI test — Needed yes/no
- Sensitivity — Pinpoint crowded panels
- Batteries — 9 V receiver; transmitter line-powered
Common mistakes
- Using on 208/240 V or DC panels outside rating.
- Ignoring wiring-fault LED meanings.
- Not reducing sensitivity to isolate adjacent breakers.
