The distribution box is making noise
Panel clicking often relates to loose connections or faulty breakers causing intermittent noises. Distribution boxes are the unsung heroes of our electrical systems, quietly managing power until something goes wrong. When they start tripping, overheating, or making strange noises, it's more than just an inconvenience - it's your home's cry for help. Resolution: Operational noise has been a question for a long time and it is generally a stacking up of factors which by themselves go unnoticed, but which together are noticed. It routes power from the service entrance and divides it among individual circuits. The panel's function is protection, housing circuit breakers that automatically interrupt the flow. The noise has been identified as coming from the electrical distribution box which is attached to a cement wall that runs up all three floors in my bedroom as a firewall.
