A surge protector is an electrical device that protects electronic appliances from power surges, or quick bursts of high-voltage electricity caused by lightning, wind damage, or faulty wiring. It works by stopping or reducing the power to a safe level. It works on most appliances, including televisions, video players, computers, and cordless telephones. It normally lasts for years, but it needs to be replaced after a high-level power surge. It is generally easy to install and readily available from hardware and electrical stores.
Make sure all your programmable appliances are connected to a power surge, including those that can withstand low-level surges such as televisions, video players, video game units, audio systems, computers, microwave ovens, and home security systems. Also connect satellite TV lines, telephones lines, and fax and modem lines to your surge protector. Check the indicator light on your surge protector regularly, especially after storms. Replace the unit after a high-level power surge to maximum safety and efficiency.
