The answer to 'why is my electrical meter circuit overload' is that your home's electrical system is drawing more power than the electrical meter can safely handle. This is often caused by too many high-power appliances or devices running at the same time, a short circuit, or an issue with the meter itself.
Some common symptoms of an overloaded electrical meter include flickering lights, tripping circuit breakers, or the meter reading higher than expected. To address this, you should first try reducing the electrical load by turning off or unplugging some devices. If the problem persists, it's best to call a licensed electrician to inspect your home's electrical system and make any necessary repairs or adjustments.
