A surge protector is an important way to protect the electronics in your home. What exactly is a surge protector? A surge protector has one job—to detect excess voltage and divert the extra electricity into the grounding wire, thus protecting your electronics from being fried. This is why all surge protectors have a grounding pin on the plug, which is the third prong on the plug. Surge protectors must be plugged into a grounded outlet for them to work as intended.
Many people think that lightning is the cause of power surges, which is true. Lightning does create power surges, but the power created from lightening power surges is so great that surge protectors can’t handle them. Your best bet for protection during a thunderstorm is to just unplug your electronics. Most victims of power surges are electronics that use a lot of power to operate. You may notice when you turn something on, such as an AC unit, the lights in your home flicker. This is because these devices demand a lot of electricity, and that puts a lot of stress on your grid and can cause surges. Electronics that need a surge protector are: computers, TV’s, stereo systems, and kitchen appliances. Anything that is expensive and has microprocessors should be hooked up to a surge protector.
All homes experience power surges, and your best protection against them is using a surge protector for expensive electronics. Without the proper diversion of electric current, your electronics can become fried and thus rendered useless. A decent surge protector is not expensive, and it can prevent replacing a damaged device.
