ELECTRICAL SCREWDRIVER – LARGE

A mains tester screwdriver is a simple yet essential tool used by electricians and DIY enthusiasts to detect the presence of electrical current in wires and circuits. It typically consists of a long, slender screwdriver with a non-conductive handle and a metal tip. The metal tip is designed to make contact with electrical terminals or wires, while the handle remains insulated to protect the user from electric shocks.

The screwdriver is equipped with a built-in neon light or LED indicator that illuminates when voltage is detected, indicating that the circuit is live. This allows users to quickly and safely determine if a wire or terminal is carrying electrical current before proceeding with electrical work such as repairs, installations, or troubleshooting.

Mains tester screwdrivers are commonly used for basic electrical tasks such as checking outlets, switches, fuses, and circuit breakers. They provide a simple and convenient way to ensure electrical safety and prevent accidents or damage caused by working on live circuits.
