AstroAI Circuit Breaker Finder, Electrical Circuit Tracer Tool with GFCI Outlet Tester, LED Indicators & Flashlight, Includes 3 Adapters, Batteries & Carrying Case, 90-120V AC, Father Day Gifts
Main highlights- [Precision Tracing Technique] - Maximize the accuracy of your circuit breaker finder by resetting the receiver away from the electrical panel to clear prior data, scanning each breaker slowly (for at least one second) near the wired terminals during the initial learning pass, and retracing the exact same path on the second pass to seamlessly isolate the correct breaker.
- [Instant Diagnostic Feedback] - The integrated outlet tester utilizes clear coding and multi-colored indicators to identify common wiring faults on the spot. It instantly highlights complex issues like open grounds, open neutrals, or reversed polarities by comparing illuminated lights against the printed diagnostic legend.
- [Dual-Sided LED GFCI Outlet Tester] - The transmitter doubles as a GFCI Outlet Tester with an automatic trip test function. Unlike traditional outlet testers that require referencing bottom light patterns, this upgraded transmitter features 3 LED indicators on both front and back, directly representing 8 wiring conditions. The dual-sided design eliminates blind spots caused by ground-up or ground-down outlets, ensuring clear visibility in any orientation.
- [Complete Accessory Kit & Carrying Case] - This Circuit Breaker Finder kit includes a 3-prong to 2-prong adapter, light socket adapter, and alligator clip adapter for expanded compatibility with various outlets and fixtures. The durable carrying case keeps the tool and accessories organized, protected, and easy to transport, making it practical for professionals on the go and organized home users alike.
- [All-in-One Functionality] - This device seamlessly integrates a circuit breaker finder, an outlet tester, and a GFCI tester into a single compact system. It allows users to safely verify wiring status, check ground-fault protection, and isolate specific breakers efficiently without needing multiple specialized tools.
- [Accurate and Reliable Tracing] - Utilizing a smart two-scan "learn and locate" process, this advanced breaker finder completely eliminates panel guesswork. The receiver memorizes the panel's signals during the first scan and then precisely pinpoints the correct breaker on the second pass using continuous audible beeps and distinct red visual indicators.
