## Overview

The Southwire 40116N is a professional-grade non-contact AC voltage tester detecting 100-600VAC with audible and visual alerts. 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.

Review: Works Great! Makes Life Much Easier! - After years of using multimeters to determine if a circuit is live, I finally decide to buy a non-contact voltage tester. Boy, am I happy that I did. The dangerous part of working on 110 V circuits is to try to get to the black (line voltage, hot wires) behind a light switch or plug, along with neutral (white). In my case, the yahoos who owned the house in the past did something beyond goofy, going into stupid territory. They spray painted the wires all white when they painted the walls. Now, imagine trying to probe the wires and not being sure what's what because they are all the same color! Even if it's different colors, there's always the risk of an electrical shock when you remove the wire nuts securing the connections. You're also holding the probes, plus the multimeter itself. If something slips, your instinct is to catch it, which means you might brush against a live wire. Having a NCVD makes life a lot easier. As always, test on a live circuit prior to each and every use, to make sure the tester still works.
