Klein Tools Outlet Tester RT310 120V Receptacle Circuit Analyzer 10 Inch Flexible Cord AFCI GFCI Dual Open Fault Detection Electrical Inspection

Isolate Complex Dual Open Wiring Faults And Verify Breaker Safeties Instantly With Multi Function Arc Fault Protection Diagnostics

The Klein Tools RT310 is a battery-operated circuit analyzer engineered for verifying AFCI and GFCI functionality across standard North American 120V AC electrical outlets. Featuring a 10-inch flexible diagnostic cord, this unit accesses tight, recessed electrical boxes and appliance receptacles that legacy rigid plug testers cannot clear. This advanced tester employs specialized circuitry to detect elusive dual-open wiring hazards, instantly identifying simultaneous open neutral and open ground configuration errors while safeguarding residential and commercial power paths.

Best Used For:

• Arc Fault Verification: Simulating precise electronic arc conditions to test and confirm that AFCI circuit breakers trip correctly to safeguard building structures.
• Recessed Outlet Diagnostics: Accessing hard-to-reach receptacles positioned behind industrial equipment, counters, or heavy mechanical appliances via a flexible cord extension.
• Dual-Fault Ground Isolation: Isolating simultaneous missing neutral and missing ground conductors during structured home inspections and panel box certifications.

Key Performance & Safety Features

• AFCI and GFCI System Testing: Artificially mimics real-world fault arcs and ground-leak leakage vectors to verify interrupter breaker compliance.
• Ten-Inch Flexible Cord: Relieves structural mechanical leverage stress on old or fragile wall receptacles while checking awkward connection profiles.
• Dual-Open Fault Interrogation: Advanced diagnostic tracking unmasks hidden multi-wire failures that standard passive neon neon bulb testers miss.
• High-Visibility Status Array: Multi-point indicator lights translate diagnostic outcomes immediately for clear tracking across common wire conditions.
• Industrial Drop Resilience: Polycarbonate and ABS composite frame handles heavy jobsite impacts and structural drop test impacts up to 6.6 feet.
• CAT III Safety Grade: Formally certified to CAT III 135V compliance parameters to ensure high-stakes diagnostic insulation protection.

What's Included

• RT310 AFCI/GFCI Outlet Tester
• Three 1.5V AAA Alkaline Batteries
• User Instruction Manual

Technical Specifications

Pro-Tip: When troubleshooting a circuit that indicates a dual-open error condition, check the next upstream junction container box; a loosely twisted wire nut terminal connection or cracked pigtailed copper lead is normally the primary path breakdown source.
