The answer to 'how does surge protection work' is that surge protectors help safeguard your home's electrical devices and appliances from sudden, powerful spikes in electrical current known as power surges. These surges can be caused by lightning strikes, faulty wiring, or malfunctioning electrical equipment. Surge protectors work by diverting the excess voltage away from your sensitive electronics, preventing damage and extending their lifespan.
Surge protectors contain specialized components like metal oxide varistors (MOVs) that act like circuit breakers, opening the circuit when they detect a surge to block the excess voltage from reaching your devices. This helps protect your TVs, computers, appliances, and other electronics from being fried or damaged by a power surge.
