The answer to 'why is my electrical panel power surge' is that a power surge in your electrical panel is often caused by a problem with the main electrical service or a faulty circuit breaker. Symptoms may include flickering lights, electrical equipment malfunctioning, or circuit breakers tripping frequently.
Some common causes include lightning strikes, issues with the utility company's power supply, faulty wiring or appliances, or a problem with the electrical panel itself. In some cases, it could also be due to a sudden high-power demand that exceeds the panel's capacity. It's important to address power surges promptly to prevent damage to your home's electrical system and appliances.
