Troubleshoot Tripping Circuit & Identify Fault

What happens here

For the second task, fixing the tripping circuit, the electrician explains that it was a challenging two-day process to locate the fault. He had to systematically disconnect around 10 outlets that were on the affected circuit. This process of elimination helped narrow down the source of the problem. He eventually found a problematic junction box, suggesting a fault or miswiring within that specific section of the circuit.

Goal: Locate the cause of the tripping circuit breaker and identify the damaged section.
