Featuring a built-in LED flashlight, auto power-off for battery conservation, and a rugged 6-foot drop-tested pen-style design, it meets UL and CAT IV 600V safety standards. Ideal for electricians and engineers, it quickly identifies live circuits in outlets, switches, and breakers, enhancing safety and efficiency on every job. ## Description Make the Southwire 40116N AC non-contact voltage (NCV) pen tester a valuable addition to your tool bag. Use it whenever you perform electrical work to identify where voltage is present. Detects voltage in wires; light switches; circuit breakers; outlets and light fixtures. Press the On button and the detection tip glows green. Move the detector tip close to the electrical wire or device being tested. If voltage is detected; the detection tip will change from green to red and begin flashing. The NCV will also beep loudly. The 40116N can also be inserted directly into electrical outlets to verify operation. All Southwire non-contact voltage detectors come with a built-in focused LED flashlight so you can illuminate dark areas. Auto power off feature helps conserve battery power. As an added safety feature; the 40116N has a low-battery self test which periodically checks the condition of the batteries. If battery voltage becomes too low; the self-test circuit turn off the non-contact voltage detector until the batteries are replaced. The 40116N is UL listed. Not designed for use with Tamper Resistant (TR) outlets. ## Features - Southwire Pen style voltage tester - AUDIBLE AND VISUAL INDICATION of AC voltage from 100-600V AC - INCREASED BATTERY LIFE: the auto power off feature increases the battery life by powering off after 5 minuets of inactivity - Green LED indicates tester is ready for use - BUILT-IN FLASHLIGHT: this non contact AC voltage detector features a built-in flashlight for user convenience in dim lighting.QUICKLY checks for the presence of live voltage on outlets, wiring, circuit breakers, lighting fixtures and switches.CAT IV 600V SAFTEY RATING, UL and CUL listed.Not designed for use with Tamper Resistant (TR) outlets ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01M24N714 | | Best Sellers Rank | #73,136 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #146 in Voltage Testers | | Brand Name | Southwire | | Color | Brown | | Customer Reviews | 4.7 4.7 out of 5 stars (2,029) | | Global Trade Identification Number | 00032886963025 | | Included Components | Southwire 40116N Non-Contact AC Voltage Detector | | Item Dimensions | 25 x 25 x 25 millimeters | | Item Type Name | Southwire 40116N Non-Contact AC Voltage Detector | | Item Weight | 0.16 Pounds | | Manufacturer | Southwire | | Measurement Type | Voltmeter | | Minimum Operating Voltage | 100 Volts (AC) | | Model | 40116N | | Number of Items | 1 | | Number of Packs | 1 | | Part Number | 59992040 | | Power Source | Battery Powered | | Specification Met | UL | | Style Name | Southwire 40116N Non-Contact AC Voltage Detector | | UPC | 032886963025 032886963032 | | Unit Count | 1 Count | | Upper Temperature Rating | 104 Degrees Fahrenheit | ## Product Details - **Brand:** Southwire - **Colour:** Brown - **Item weight:** 0.16 Pounds - **Power source:** Battery Powered - **Style:** Southwire 40116N Non-Contact AC Voltage Detector ## Images ![Southwire Tools & Equipment Southwire 40116N AC Pen Tester, NCVT Detects 100-600VAC, Non-Contact Voltage Detector with LED Flashlight, 6' Drop Test Rated, One Size, Green,Red - Image 1](https://m.media-amazon.com/images/I/31wQQIW32KL.jpg) ![Southwire Tools & Equipment Southwire 40116N AC Pen Tester, NCVT Detects 100-600VAC, Non-Contact Voltage Detector with LED Flashlight, 6' Drop Test Rated, One Size, Green,Red - Image 2](https://m.media-amazon.com/images/I/41D1lFQNkpL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: How to replace batteries?** A: At the end of the name 'Southwire' is a small recess.
