The Klein ET310 Breaker Finder and GFCI Outlet Tester: A Powerful Combination

Posted on September 9, 2023 by Philbert Jackson

Introduction

The Klein ET310 Breaker Finder with GFCI Outlet Tester is a versatile and essential tool for anyone working with electrical outlets and fixtures. Designed to be user-friendly, this device combines two diagnostic tools into one, making it an invaluable asset for professionals and DIY enthusiasts alike. By incorporating the new Klein Tools Voltage Tester ET45, you have access to a comprehensive circuit tracing and testing solution.

Advantages

Easy-to-Use and Accurate Locator

The Klein ET310 Breaker Finder with GFCI Outlet Tester is remarkably user-friendly, providing precise and reliable results. Its intuitive design simplifies the locating process by plugging the transmitter into the outlet in question and using the receiver to find the corresponding circuit.

Transmitter Doubles as GFCI Receptacle Tester

With the transmitter also functioning as a GFCI receptacle tester, this device offers enhanced convenience and efficiency. You can quickly and easily test the functionality of GFCI outlets, ensuring the utmost safety and reliability.

Built-In Storage for Transmitter

The transmitter conveniently plugs into the end of the receiver when not in use, keeping the pair together and minimizing the risk of misplacing either component. This smart design feature ensures that you always have both tools readily available for use.

Automatic Shutdown for Battery Conservation

To maximize battery life, the Klein ET310 Breaker Finder with GFCI Outlet Tester includes a 3-minute automatic shutdown feature. This energy-saving function helps preserve the included 9-volt battery, ensuring that your tool is always ready to go when you need it.

Shortcomings

Occasional Ghost Voltages

While the Klein ET310 Breaker Finder with GFCI Outlet Tester is an exceptional tool, it may occasionally detect ghost voltages. Although this is not a major issue, it is recommended to verify the accuracy of the readings by flipping the circuit breaker.

Recommendation

The Klein ET310 Breaker Finder and GFCI Outlet Tester is an incredibly useful set of tools that work in harmony to simplify your work. With its quick and accurate locating capabilities, this device significantly reduces the time and effort required for verification and diagnostics. Whether you’re a professional electrician or a DIYer, this tool is a valuable addition to your toolkit.

Up Power Creek

As the saying goes, going to work without the essential tools is like swimming up a creek without a paddle. However, with the Klein ET310 Circuit Breaker Finder and GFCI Outlet Tester by your side, you’ll never find yourself in such a predicament. Its innovative combination of diagnostic tools sets it apart from the competition, making your work more efficient and effective.

Operating this tool is a breeze. Simply plug the transmitter into the outlet you’re working on and use the receiver to locate the circuit at the panel. The receiver’s tip glows green when powered on, and once you’ve found the correct circuit, a red light and audible indicator confirm your success.

To ensure that you never misplace either component, the receiver mimics an outlet, allowing you to plug in and store the transmitter securely. This thoughtful design keeps everything together and prevents any unnecessary hassle.

The Ghosts of Circuits Past

It’s worth noting that the Klein Breaker Detector Receiver may occasionally detect phantom voltages, resulting in a flashing red light and an audible alert. However, this is a minor inconvenience that can be easily resolved by verifying the circuit with a breaker flip. Seasoned professionals understand the occurrence of false positives, but it’s important to be cautious and aware, especially for DIYers.

To test a GFCI circuit, simply press the transmitter’s gray button to simulate a trip. If it fails, replace it in sequence. The transmitter is equipped with right and wrong wiring legends, which correspond to different combinations of its three LEDs, simplifying the testing process.

Klein tools are renowned for their durability, and the circuit breaker detectors are no exception. With the ability to withstand a 6.6-foot drop, this tool is built to last. It is also CAT II 120V rated, ensuring its safety and reliability. Additionally, the built-in 3-minute auto-off timer helps conserve the onboard battery, maximizing its lifespan.
