Perform Initial Voltage Test on Wires

What happens here

Using a non-contact voltage tester (often called a 'hot stick' or 'voltage pen'), carefully check all exposed wires within the electrical subpanel for live voltage. As demonstrated in the video, the electrician checks multiple wires and finds that 'every wire was live (hot), including the ground wire.' A ground wire should never be live, indicating a critical and dangerous wiring fault. This initial test helps confirm if the panel has unexpected live circuits, which is a major hazard.

Goal: Check all wires for unexpected live voltage, especially the ground wire.
