Strip Romex Jacket and Ground Junction Box

What happens here

The outer jacket of the Romex wire inside the junction box is carefully stripped using a utility knife. This exposes the individual insulated wires: black (hot), red (hot), white (neutral), and bare copper (ground). It's crucial to avoid cutting the insulation of the inner wires. A pre-made ground tail, typically purchased at a hardware store like Home Depot, is then screwed into the metal junction box to ensure it is properly grounded. This is a critical safety step when working with metal electrical boxes.

Goal: Prepare Romex wires and ensure box is grounded
