Southwire NCV Detector for 100-600V AC

Southwire's 40116N AC non-contact voltage (NCV) pen tester is a valuable addition to any electrician's tool kit. It is designed to detect the presence of voltage in a variety of electrical components, including wires, light switches, circuit breakers, outlets, and light fixtures. This versatile tool can be used to ensure safety and identify potential issues during electrical work.

The detection process is straightforward: simply press the On button, and the detection tip will glow green, indicating that the device is ready for use. Then, move the detector tip close to the electrical wire or device being tested. If voltage is present, the detection tip will change from green to red and begin flashing, accompanied by a loud beeping sound from the NCV. This clear visual and audible feedback helps users quickly and accurately identify the presence of voltage.

In addition to its voltage detection capabilities, the 40116N can also be inserted directly into electrical outlets to verify their operation. This feature is particularly useful when checking the functionality of outlets during installation or maintenance.

To enhance usability, the 40116N is equipped with a built-in focused LED flashlight, allowing users to illuminate dark areas during testing. This added convenience can be especially helpful in dimly lit or cramped work environments.

The device also features an auto power-off function, which helps conserve battery life by automatically turning off the NCV after 5 minutes of inactivity. This energy-saving feature ensures the 40116N is always ready for use when needed.

For added safety, the 40116N has a low-battery self-test function that periodically checks the condition of the batteries. If the battery voltage becomes too low, the self-test circuit will automatically turn off the non-contact voltage detector, preventing inaccurate readings and potential hazards.

The 40116N is UL listed and has a CAT IV 600V safety rating, making it suitable for use in a wide range of electrical applications. It is not, however, designed for use with tamper-resistant (TR) outlets, which may require a specialized tool for testing.

In summary, the Southwire 40116N AC non-contact voltage pen tester is a reliable and versatile tool that can enhance the safety and efficiency of electrical work. Its intuitive design, audible and visual voltage detection, built-in flashlight, and safety features make it a valuable addition to any electrician's toolkit.
