The SureTrace Plus Circuit Tracer provides fast and accurate breaker, conductor, and fault finding on energized/de-energized electrical systems, including 3-Phase. Leave your second tester behind and perform basic troubleshooting tasks using the transmitter’s patent-pending auto continuity tester, voltage indication (24 to 600V AC and 12 to 600V DC), and DC polarity indication features. Easily trace circuits and locate breakers in all positions and low-light conditions using the integrated work light and the receiver's dual high-visibility displays — a patented TightSight secondary display and 180° rotating main display. You can also check for the presence of AC voltage from 24 to 600 VAC usng the receiver's built-in NCVT. Troubleshoot without the need for a second person using advanced CertainCircuit technology that alerts you when the circuit is energized or de-energized at the panel and at the other end of the circuit. With a CAT III 600V rating, the SureTrace Plus Circuit Tracer is your fast, accurate circuit troubleshooting solution on both energized and de-energized systems. RELIABLE TRACING: Detect breakers, conductors, fuses, dead shorts, and splice errors in all electrical systems up to 600V AC/DC, including 3-phase, with speed and accuracy using this ETL Certified CAT III circuit tracer LIGHTEN YOUR TOOLBELT: Identify shorted conductors, determine voltage levels, and detect AC voltage — no second tester needed — when using the new patent-pending transmitter features and receiver with a built-in NCVT VOLTAGE INDICATORS: Transmitter indicates DC polarity and eight different voltage levels between 24V to 600V AC and 12V to 600V DC
