Surge Protection

From flat-screen televisions to computers, refrigerators, and even blenders, our homes are loaded with electronic equipment that could be damaged by a power surge – a momentary rise in the flow of electricity. In normal household wiring, the standard voltage is 120 volts. When the voltage rises above this level, this is considered a power surge.

The electronic devices that are common in our homes today contain many delicate components that are vulnerable to power surges. Microprocessors, which are an integral part of all computers as well as many home appliances, are particularly sensitive to surges.

To help protect your electronic equipment, we suggest investing in one or both of the following types of surge protection:

Point-of-Use Surge Protection

Point-of-use surge protectors should be installed on all electronic equipment in your home.  This most common surge protection device is a type of power strip that can handle up to 6,000 volts. Surge suppressors can be purchased at most hardware or home-improvement stores. Be careful to buy a suppressor that offers surge protection. Standard power strips – which look nearly identical to a surge suppressor – do not offer this protection.

When purchasing a surge suppressor, pay attention to the product’s Underwriters Laboratories (UL) ratings. UL is an independent, nonprofit company that tests electronic products for safety. Be sure that the product is listed as a transient voltage surge suppressor and meets the criteria for UL 1449, UL’s minimum performance standard for surge suppressors.
