I used to run back and forth between outlets and the breaker panel trying to find the right switch. This kit made the process much faster and clearer. The LCD display helped me confirm the signal instead of guessing.

The backlit screen is a huge help when working near a dim breaker box. I also like that it checks outlet wiring and GFCI protection, so I don’t need to carry several separate testers.

Still Guessing Which Breaker Controls Which Outlet?
Try the Tyiiplus® LCD Circuit Breaker Finder Kit!
Traditional breaker tracing often requires two people, repeated switching, and a lot of trial and error.
Our Solution:

The KT301P circuit breaker finder helps locate the correct breaker quickly while displaying signal strength for more confident identification.

Many basic testers only show simple light indicators, leaving you unsure about the actual voltage or wiring condition.
Our Solution:

The large LCD screen displays real-time voltage from 30–150V, outlet wiring status, and clear diagnostic information.

Standard outlet testers may not provide enough detail when checking GFCI outlets or wiring faults.
Our Solution:

The transmitter works as a GFCI outlet tester with automatic trip testing, red/green LED indicators, and diagnosis for 7 common wiring faults.

Some electrical testers require direct contact or multiple tools to identify live voltage areas.
Our Solution:

The receiver includes a non-contact voltage test function, helping detect nearby voltage sources quickly and safely.

I bought it mainly for breaker finding, but the outlet tester and GFCI function ended up being just as useful. It feels like a smart all-in-one tool.

Very convenient kit. The adapters make it easier to test different situations, and the LCD screen is much better than relying only on blinking lights.
