Installation Notes

This tool is used by licensed electricians for circuit identification and panel labeling work. No power interruption is required during use, but always follow NFPA 70 (NEC) safe work practices when working near energized electrical panels. Keep the transmitter plugged into the outlet of the circuit being traced and use the receiver to scan breakers or fuses at the panel until the signal is detected. Do not use on circuits operating outside the stated voltage range.
