What happens here

The technician proceeds to remove a circuit breaker from the panel, explaining that it needs to be pulled straight back and then out to avoid tripping adjacent breakers. He uses a flathead screwdriver to loosen the terminal screws on the breaker. He notes the color-coding of the wires (brown, orange, yellow) and ensures they are labelled for reinstallation. He explains that for this type of breaker, it's crucial to tighten the lugs only by hand to ensure a proper connection without overtightening or stripping. He highlights that the "teeth" on the back of the breaker must align with the bus bars for correct installation.

Goal: Safely remove a potentially faulty circuit breaker and inspect its connections.
