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. For more information on Surge Protection, see below.

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.

Lightning Protection - Questions & Answers

Whole House Surge Protection

Whole House Surge Protection offers homeowners protection against damaging surge currents throughout the electrical circuitry of homes and buildings.

Many homeowners already use a Surge Protective Device (SPD) on computers, laptops, printers, and other devices. These SPDs are intended to protect specific devices.

Studies by the Institute of Electrical Engineers (IEEE) indicate power line disturbances occur about four times a day throughout the USA. Power line disturbances can result from nearby lightning strikes, power outages from any means including power poles hit during an auto accident. Transient voltage spikes can also result from electric motor starting and the use of compressors, fluorescent lights, or voltage fluctuations from the utility company.

A Surge Suppressor could also be called a “Surge Diverter”. The suppressor attempts to limit or block excessive voltage to electronic devices and appliances. So, a $79 surge suppressor can save thousands in replacement costs for A/C compressors, refrigerators, freezers, and home theatres.

Here are the major components of an effective Whole House Surge Protection System:

  1. AC Power Protection - This is the main component which protects the Main Breaker Panel and all connected circuits with protection against surges up to 140,000 amps. Most other SPDs are considered downline protective devices except for telephone, data, and cable.
  2. AC Power Strip and Wall-Mount SPDs offer downline protection for computers, refrigerators, freezers, TVs and other sensitive electronics. 
  3. Alarm Panel Protection
  4. Air Conditioning Compressors
  5. CATV Protection
  6. Gate Operators
  7. Network and Router Protection
  8. Video Surveillance Protection
  9. Voice, Data, and Signaling Protection

Benchmark Electric can install a surge suppressor for each Main Breaker Panel, plus downline protection for A/Cs. These services require an electrician to install.

Optional protection for telephone, cable, and Internet is available. Homeowners are encouraged to consider additional downline SPDs for computers and other electronic devices. These simple, plug-in devices can be installed by you or us in just a few minutes time.
