Klein Tools ET310KIT AC Circuit Breaker Finder Kit, Electric Tester, GFCI Tester, Leads, Adapters with Case

Overview

The Klein Tools ET310KIT is a set of electrical testing instruments designed for identifying and testing circuit components. The kit contains an AC circuit breaker finder, an electric tester, a GFCI tester, leads, adapters, and a protective case.

Components

• AC Circuit Breaker Finder: A device used to locate the breaker that controls a specific circuit by detecting the current flow when the breaker is closed.
• Electric Tester: A tool for checking the presence of voltage and continuity in electrical circuits.
• GFCI Tester: An instrument for verifying the correct operation of ground‑fault circuit interrupters.
• Leads: Conductive cables that connect the testers to the points being examined.
• Adapters: Connectors that allow the leads to attach securely to the testing devices.
• Case: A storage container that holds all components of the kit for easy transport and organization.

Usage

The kit is intended for electricians, maintenance personnel, and homeowners who need to locate circuit breakers and verify the integrity of electrical outlets. The process generally involves the following steps:

1. Identify the target circuit: Determine which outlet or device requires testing.
2. Apply the electric tester: Use the electric tester and leads to confirm that voltage is present at the outlet or device.
3. Use the GFCI tester: Verify that a GFCI outlet properly interrupts current when a fault condition is simulated.
4. Find the breaker: Connect the AC circuit breaker finder to the outlet using the leads. The finder will emit a signal or indicator that points to the breaker controlling that circuit.
5. Record or adjust: Once the breaker is identified, it can be labeled or switched to test for proper functioning.

All tools in the kit are designed for quick, reliable diagnostics. The leads and adapters allow for flexible connection to various outlet types and breaker configurations.

Packaging and Organization

The included case serves as a convenient storage solution. It keeps the tester, breaker finder, leads, and adapters together, reducing the likelihood of loss during travel or in the field. The case protects the components from damage and provides a compact form factor for carrying the kit to job sites.

Key Features

• Integrated set of tools for locating breakers and testing electrical circuits.
• Includes both voltage and ground‑fault testing devices.
• Leads and adapters facilitate secure connections between devices and electrical points.
• All components are housed in a case for easy transport.

Practical Applications

Typical tasks performed with the ET310KIT include:

• Locating the breaker that supplies power to a specific outlet or fixture.
• Confirming that an outlet has active voltage before work begins.
• Testing that a GFCI outlet correctly disconnects power under fault conditions.
• Ensuring that breakers are properly labeled and that the correct breaker controls each circuit.

These tasks are common in residential, commercial, and industrial electrical maintenance, providing a quick method for identifying circuit issues and verifying safety devices.

Compatibility and Safety Considerations

The components in the kit are designed for standard AC electrical systems. Users should follow local electrical codes and safety guidelines when performing testing. While the kit is a useful diagnostic aid, it is not a replacement for comprehensive safety training or professional electrical assessment.

Storage and Maintenance

To preserve the functionality of the tester, GFCI tester, and breaker finder, keep the components dry and free from extreme temperatures. When the kit is not in use, store it in the supplied case. Periodic inspection of the leads and adapters for wear or damage can help maintain reliable connections during testing.
