A surge protector is a device that protects electrical equipment from voltage spikes. These spikes can be caused by a number of factors, including lightning strikes, power outages, and faulty wiring. Surge protectors work by diverting excess voltage away from the equipment and into the ground. This helps to prevent damage to the equipment and can also help to prevent fires.
Surge protectors are available in a variety of shapes and sizes, and they can be used in both residential and commercial settings. Some surge protectors are designed to be plugged into a wall outlet, while others are hardwired into an electrical panel. The type of surge protector that you need will depend on the specific needs of your application.
