It detects live voltage without requiring direct contact with a conductor, reducing exposure risk during live-circuit testing. The unit covers two detection ranges: 100 to 1,000 VAC for standard line-voltage work and 12 to 1,000 VAC for low-voltage applications. At 6.5 inches in length and 1 inch in width, it fits easily in a tool pouch or chest pocket. Power comes from two AAA 1.5V batteries. Licensed electricians, HVAC technicians, and maintenance professionals rely on non-contact voltage testers as a first-check safety tool before touching any conductor or terminal.\u003c\/p\u003e\n\u003cp\u003eThis detector suits a wide range of electrical work, including panel inspection, outlet and switch testing, junction box verification, and low-voltage circuit checks. The 12 to 1,000 VAC lower range makes it useful for doorbell transformers, thermostat wiring, and other low-voltage control circuits in addition to standard 120V and 240V branch circuits. The advanced dual-range capability means a single tool covers both control-voltage and line-voltage environments without swapping instruments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDual detection ranges: 12 to 1,000 VAC and 100 to 1,000 VAC for broad application coverage\u003c\/li\u003e\n  \u003cli\u003eNon-contact sensing eliminates the need to touch live conductors during voltage verification\u003c\/li\u003e\n  \u003cli\u003eCompact form factor at 6.5 inches tall and 1 inch wide fits standard tool pouches\u003c\/li\u003e\n  \u003cli\u003ePowered by 2 AAA 1.5V batteries for field-ready portability\u003c\/li\u003e\n  \u003cli\u003eSuitable for both low-voltage control circuits and full line-voltage systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for general-purpose AC voltage detection across residential, light commercial, and industrial electrical systems operating within the 12 to 1,000 VAC range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eNon-contact voltage testers are used by licensed electricians and qualified technicians as a preliminary safety check before servicing electrical circuits. Always de-energize and lock out or tag out circuits per OSHA and NEC guidelines before performing hands-on work, even after a no-voltage indication. Verify the tester is functioning correctly by testing it on a known live source before and after each use. Battery replacement should be performed with the unit away from any energized equipment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Voltage Detector\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Range\u003c\/strong\u003e: 12 to 1,000 VAC \/ 100 to 1,000 VAC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePower Supply\u003c\/strong\u003e: 2 AAA 1.5V Batteries\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 6.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SOUTHWIRE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 40150N\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWIRE","offers":[{"title":"Default Title","offer_id":51283978191154,"sku":"40150N","price":77.8,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309279019.jpg?v=1781064851","url":"https:\/\/voomisupply.com\/products\/southwire-40150n-dual-range-non-contact-ac-voltage-detector","provider":"Voomi Supply","version":"1.0","type":"link"}
