The answer to 'why is my fuse box circuit overload' is that your home's electrical system is drawing more current than the circuit breaker or fuse is designed to handle. This can happen for several common reasons, such as too many high-wattage appliances running on the same circuit, a short circuit in the wiring, or a malfunctioning electrical device.
Some common symptoms of an overloaded circuit include flickering lights, outlets that don't work, or the circuit breaker tripping frequently. To resolve the issue, you'll need to identify and address the root cause. This may involve redistributing the electrical load, repairing faulty wiring, or replacing a broken appliance. If the problem persists or you're unsure of the cause, it's best to call a licensed electrician to diagnose and fix the issue properly and safely.
