While power surges typically last less than a second, they can quickly damage your electronics and electrical appliances if appropriate protection isn’t in place. Power surges are often caused by outside sources such as lightning or electrical updates conducted by utility companies.
Your own appliances can cause surges as well; for example, if powerful electronics or appliances are running all at once (such as your washing machine, air conditioner, or water heater), you may experience a sudden power surge if your electrical system is unable to handle the high demand.
Using power strips or uninterruptible power supplies with surge protection are great for protecting your electronics such as your computer or television. But they’re not able to protect the rest of your home’s larger appliances and equipment. If a power surge affects even just a single unprotected outlet, all of your electronics and appliances can crash.
This is why whole-house surge protection is crucial. By protecting all of your electrical devices and appliances, you can avoid thousands of dollars in damage.
