The answer to 'surge protector sparking' is that a sparking surge protector is a sign of a serious electrical issue that requires immediate attention. This can be caused by a power surge, faulty wiring, or the surge protector itself failing. Symptoms include visible sparks, smoke, or burning odor coming from the surge protector.
It's important to unplug the surge protector immediately and stop using it. Do not attempt to inspect or repair the surge protector yourself, as this can be extremely dangerous.
