Our homes are filled with sensitive electronics. These devices are easily damaged by common power surges, and lightning strikes. It only takes a lightning storm near your home to create a high – energy electrical surge that can enter your home and destroy your appliances, TVs, stereo equipment and almost all other modern electrical products.

Surges are unwanted energy that travels down a conductor and passes through your electronics and electrical equipment. Lightning is one of the most damaging sources of surges entering your home. Other sources include utility grid switching, other users on the power line, and internal surges from air conditioners and  power tools.


Most modern appliances contain smart computer chips. These digital circuits are vulnerable to surges. The following are some examples of appliances that contain computer chips:

  • Stoves, Refrigerators, Dishwashers and other counter-top appliances
  • Microwave ovens
  • Air conditioners
  • Washers and Dryers
  • Lighting controls
  • Garage door openers


Electronic equipment is jammed with digital circuits. In this computer age, devices are getting smaller, faster and more complicated. The following electronic devices are products commonly found in homes.

  • Televisions
  • Stereo systems
  • Entertainment centers
  • Personal computers
  • Fax machines
