It's important to protect all your electronic devices, not just computers, from surges. Printers, televisions, appliances and computer peripherals all require protection. However, it can be inconvenient to use individual surge protectors on all devices that need protection. One solution is to install a whole-house surge protector as shown in this photo. The device is installed by an electrician and is attached to your circuit breaker panel. Whole-house surge protectors function like other surge protection devices, but they protect all electrical devices in the house at once. The typical cost of $200 to $300 (installed) is generally less than buying individual surge protectors for every electrical device in your home.
