Primary Use Case: How to Test Live Wire with Test Pen

A Total test pen is primarily used to check whether a wire or electrical point is live (has voltage) before touching or working on it. This simple step significantly reduces the risk of electric shock.

How to Use Test Pen Safely (Step-by-Step)

1. Hold the insulated handle of the test pen firmly.
2. Place your finger on the metallic contact at the top of the pen.
3. Touch the tip of the test pen to the wire, terminal, socket hole, or switch screw.
4. If the internal neon bulb or indicator lights up, the wire is live.
5. If there is no light, the circuit is not live (or voltage is below detection range).

This method answers the most common user question: how to use test pen and how to test live wire with test pen safely and correctly.
