Surge suppressors often look like power strips but are also designed to eliminate sudden surges in voltage that can damage appliances. Look for the label “UL Listed Transient Voltage Surge Suppressor” to make sure you are not dealing with a simple power strip.

Power surges can be due to lightning, a surge coming from the power company, or even an electric motor starting in your own home. Traditional appliances such as refrigerators or washers typically do not need suppressors, but computers do. Keep in mind that as newer appliances and home automation systems now use computer chips, they can also be vulnerable to power surges.

Suppressors typically include a power switch and sometimes a reset button that is used if a power surge triggered the suppressor’s own protection. Note that a very strong surge such as a direct lightning strike will permanently damage the suppressor. Typically, a green light indicates whether the unit is functioning properly.

Some suppressors also allow for the connection of a phone line. Since the phone wiring coming into your home can also carry a surge, these units are used to protect telephones, fax machines, modems, and other devices, which connect to the phone line through the suppressor.

When looking for a suppressor, consider the following:
  • The number of outlets that it can support
  • How the outlets are laid out on the strip. Since a lot of computer accessories use a transformer with a built-in plug, these may prevent you from using some of the outlets. There should be enough space on the strip to accommodate everything that needs to be connected.
  • The amount of energy (in Joules) that it can absorb (the higher the number the better)
  • A good suppressor should meet the requirements of UL 1449, the standard for transient voltage suppressors.
  • Whether you need to protect your phones
  • Some suppressors will state their Suppressed Voltage Rating (the lower the number the better), and their response time (in nanoseconds, the lower the better)
  • If you anticipate the need for multiple suppressors,

    you may want to consider a whole house suppressor. A whole house suppressor connects directly to the panel where power comes into the home. Installation of whole house suppressors is typically done by a licensed electrician.
