The answer to 'why is my circuit breaker power surge' is that a circuit breaker can trip or 'power surge' due to an overload, short circuit, or ground fault in the electrical system. This is a safety feature to prevent damage and fire hazards. Common causes include too many appliances or devices on a single circuit, faulty wiring, or a problem with the circuit breaker itself.
If your circuit breaker keeps tripping, it's important to identify and address the underlying issue. This may involve reducing the electrical load, inspecting the wiring, or replacing a malfunctioning circuit breaker. In some cases, you may need to call a licensed electrician to diagnose and resolve the problem, especially if it involves complex or potentially dangerous electrical work.
