The answer to 'why is my electrical meter circuit overload' is that your home's electrical system is drawing more power than the meter can safely handle. This can be caused by a variety of issues, such as a major appliance failure, a wiring problem, or simply using too many high-power devices at the same time.
Some common symptoms of an electrical meter circuit overload include flickering lights, tripped circuit breakers, or even a complete power outage. If you're experiencing any of these issues, it's important to address the problem right away to prevent further damage to your electrical system.
