Test for Voltage with Non-Contact Tester

What happens here

The presenter demonstrates the use of a Klein Tools non-contact voltage tester. This tool is essential for safety, as it allows you to check if a wire is live without physical contact. When touched to a wire with no voltage, the tester glows green. When touched to a live wire (after power is restored), it glows red and often beeps, indicating the presence of voltage. Always use this tool to confirm a circuit is dead before working on it and to verify power after completing work.

Goal: Safely verify presence or absence of electrical voltage
