I tackled an issue with flickering lights in a residential home this afternoon. The troubleshooting process involved checking the electrical panel for loose connections and testing the voltage stability on affected circuits. I discovered faulty wiring at several junction boxes which was causing inconsistent current flow. After securely re-wiring these connections and replacing older, degraded wires, the flickering issue was resolved. The entire electrical system was then inspected to ensure it was safe and met current electrical standards.
