The answer to 'why is my electrical meter dimming lights' is that a dimming electrical meter is often a sign of an overloaded electrical system or a problem with the meter itself. This can cause lights to dim or flicker when other appliances or devices are turned on.
Some common causes include: an outdated or undersized electrical panel, too many high-wattage devices running at the same time, loose or corroded connections, or a malfunctioning meter. Symptoms may include flickering or dimming lights, power surges, or breakers tripping frequently.
