Emergency Electrical Repairs: A homeowner reported a complete power outage in part of their home, accompanied by a loud buzzing sound from the electrical panel. Upon arrival, we identified a loose breaker connection that was arcing and causing the buzzing noise. We safely de-energized the panel, repaired the connection, and tested all affected circuits. Power was fully restored, the buzzing stopped, and the system was confirmed to be operating safely, preventing potential hazards.
