Lightning protection systems were first pioneered by Benjamin Franklin’s lightning rod. Today, these lightning rods or “air terminals” are an integral component in the modern lightning protection system.

Lightning rods comprise just one of three major components of a complete Lightning Protection System. Thick, copper conductor cables and ground rods make up the other two components. When bonded together, the system provides a safe path to ground for lightning electrical current.

Lightning protection systems were first pioneered by Benjamin Franklin’s lightning rod. Today, these lightning rods or “air terminals” are an integral component in the modern lightning protection system.

Lightning rods comprise just one of three major components of a complete Lightning Protection System. Thick, copper conductor cables and ground rods make up the other two components. When bonded together, the system provides a safe path to ground for lightning electrical current. 

Let’s examine and review the three major components of a Lightning Protection System:

1. Lightning Rods, also known as “Air Terminals”, are thick 12"-18" vertical copper rods. Air terminals are installed at the highest points on a structure’s roof and spaced no more than 30-feet apart. Acting as a “terminal” for lightning discharges, the rods pass the discharge to the other two components.

2. Conductor Cables are very thick copper or aluminum cables which connect Air Terminals together and provide for the safe passage of electrical discharges to ground.

3. Ground Rods are long copper, or aluminum rods buried deep into the ground. Conductor cables are bonded to each ground rod. Most structures will have a ground rod installed at each corner.

A properly installed Lightning Protection System also includes Whole House Surge Protection to protect the integrity of the structure’s electrical system. Click here for more information on Whole House Surge Protection.

Benchmark Electric is an experienced installer of Lightning Protection Systems. The major components are made of copper in most installations. Aluminum components are used on structures with a metal roof.

We also offer Surge Protective Devices (SPDs) to protect telephone lines, cable / satellite, and all major appliances throughout the home.
