Surge Protection

Summary: This article explains what surge devices are available and how they can help protect your home electronic devices.


Surge Protection at the Point of Use for Home Wiring Protection


Surge Protection at the Point of Use


Point of use products provide a second line of defense.


Homeowners can reinforce the protection provided by a point-of-entry protection device by installing surge protectors (strips) and low-voltage surge suppressors.




Plug In Power Strips with Surge Protection

This line of defense is at the point of use.

Here, homeowners can reinforce point-of-entry protection by installing plug-in surge protectors (strips) into grounded wall receptacles where sensitive electronic equipment is located. These plug-in protectors, which generally have much lower limiting voltages than entry protectors, defend against externally and internally generated surges that travel through power, phone, data, and coaxial lines.

Surge Protection at the Point of Use

Point of use products provide a second line of defense. Homeowners can reinforce the protection provided by a point-of-entry protection device by installing surge protectors (strips) and low-voltage surge suppressors.

Surge protectors plug into grounded wall receptacles where sensitive electronic equipment is located. These devices defend electronic components against surges from outside, and internally generated transient events (surges) that travel through AC power lines. Low-voltage surge suppressors defend electronic components against surges from outside, and internally generated transient events (surges) that travel through phone, data, and coaxial lines. These plug-in protectors generally have much lower limiting voltages than entry protectors, and provide better protection for electronic equipment.

As a homeowner, where do you install these devices?

Simply put—anywhere you have got expensive or sensitive electronic equipment like Computers, DVD Players, VCR's, Fax Machines, PCs with Modems, Satellite Systems, Stereo Systems, Copiers, Printers and Scanners, Home Entertainment Systems and TV's.

Start by physically inspecting each room to determine which electronics need point-of-use surge protection, what kind of lines and how many plugs you have, and what type of signal lines are connected to each system.

As a rule of thumb, all types of equipment with signal lines, such as phones, cable TV, and satellites, should be equipped with low-voltage surge suppressors, which are specially designed to protect the signal lines.
