Using advanced proprietary circuitry, the HGT6520 detects low ground wire resistance below 10 ohms and provides a single LED readout that confirms correct wiring without requiring the user to interpret a dual-indicator chart. The high-impact ABS housing carries a 250-pound crush rating and is built to survive drops of up to 10 feet, making it a practical field tool for rough conditions.\u003c\/p\u003e\n\u003cp\u003eThe HGT6520 is suited for residential and light commercial electrical inspections, service calls, and new construction walk-throughs. It plugs directly into standard 120-volt outlets and includes a built-in GFCI test function for outlets wired in parallel, allowing the technician to trip downstream GFCI protection on a shared circuit. Electricians, home inspectors, and service contractors use this tester to identify miswired outlets, missing grounds, and failed GFCI devices quickly during inspection rounds.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDetects ground wire resistance below 10 ohms using advanced proprietary circuitry\u003c\/li\u003e\n  \u003cli\u003eSingle LED readout indicates correct wiring without a dual-indicator decoding chart\u003c\/li\u003e\n  \u003cli\u003eBuilt-in GFCI test function covers outlets wired in parallel on shared circuits\u003c\/li\u003e\n  \u003cli\u003eHigh-impact ABS housing rated to 250 pounds of crush force\u003c\/li\u003e\n  \u003cli\u003eSurvives drops of up to 10 feet for demanding field use\u003c\/li\u003e\n  \u003cli\u003ePackage quantity of 5 units per order\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 120-volt GFCI-protected outlets in residential and light commercial electrical systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tester is installed and operated by licensed electricians or qualified inspectors. No tools or wiring work is required to use the tester — simply plug it into the outlet under test. Always confirm the circuit voltage matches the tester rating before use.
