The answer to 'why is my electrical wiring power surge' is that a power surge is typically caused by a sudden spike in the electrical current flowing through your home's wiring. This can happen due to various reasons, such as lightning strikes, faulty appliances, or problems with the power grid.
Common symptoms of a power surge include flickering or dimming lights, damage to electronic devices, and tripped circuit breakers. To address the issue, you should first try resetting any tripped breakers and unplugging any damaged appliances. If the problem persists, it's best to call a licensed electrician to inspect your home's wiring and identify the root cause of the power surge. They can then recommend the appropriate solution, which may involve installing surge protectors, upgrading your electrical panel, or making other necessary repairs.
