Klein Tools RT310 AFCI GFCI Outlet Tester for 120V North American Receptacles with 10-Inch Flexible Cord Detects Dual-Open Wiring Faults and Arc Flash

Comprehensive Safety Diagnostics: The Klein Tools RT310 AFCI/GFCI Circuit Analyzer

The Klein Tools RT310 is a professional-grade electrical tester designed to ensure the safety and integrity of North American 120V electrical systems. Engineered for high-stakes diagnostics, this battery-operated device goes beyond simple light-sequence testers by accurately inspecting both AFCI (Arc-Fault Circuit Interrupter) and GFCI (Ground-Fault Circuit Interrupter) devices. Using a unique, patent-pending test method, the RT310 simulates real-world arc fault and ground fault conditions to verify that your safety breakers are fully operational. Whether you are performing a home inspection or certifying a commercial build, the RT310 provides the reliable verification needed to protect against electrical fires and shock hazards.

Flexibility and advanced detection define the RT310’s superior design. Featuring a 10-inch flexible electrical cord, this tester provides easy access to receptacles located in cramped spaces, behind heavy appliances, or at awkward angles that rigid plug-in testers cannot reach. It features patent-pending technology capable of detecting complex "Dual-Open" wiring faults, identifying simultaneous open neutral and open ground wires that standard testers often miss. Built to withstand the rigors of the jobsite with 6.6-foot drop protection and a CAT III 135V safety rating, the RT310 is equipped with intuitive visual indicators and an auto-power off function to ensure your tool is always ready for the next inspection.

Key Features

• AFCI & GFCI Testing: Specifically simulates arc fault and ground fault conditions to ensure safety devices trip correctly.
• 10-Inch Flexible Cord: Maneuver easily into tight spaces or hard-to-reach outlets without stressing the receptacle.
• Dual-Open Fault Detection: Patent-pending technology identifies simultaneous open neutral and open ground wiring errors.
• Visual Wiring Indicators: Clear, high-visibility lights provide immediate identification of common wiring faults.
• Jobsite Durability: Rugged PC/ABS housing is drop-tested up to 6.6 feet and carries a CAT III 135V safety rating.
• Battery Conservation: Integrated low battery indicator and 2-minute auto-power off feature to maximize runtime.

Specifications

Pro-Tip: Because AFCI/GFCI testers simulate an actual fault to trip the breaker, they rely on the electrical system's grounding to work. If you are testing an older home with ungrounded 2-wire outlets, the GFCI test button on this tool will not trip the device, but the outlet's internal test/reset buttons should still be used to verify local protection.
