What Is A Lightning Protection System?

A lightning protection system does not attract, repel, or prevent a lightning strike. Rather, it provides specified pathways on which lightning can travel, carrying the destructive power of the lightning strike safely into the ground.

What Is Lightning?

Lightning is a natural, high-voltage electrical discharge between a cloud and the ground or within a cloud, typically accompanied by a bright flash and loud thunder. Lightning strikes the United States about 25 million times each year, causing an estimated five billion dollars in damage, hundreds of injuries, and many tragic deaths.

What is a Lightning Protection System?

Fortunately, lightning protection systems complying with nationally-accepted standards are a proven and cost-effective way to protect buildings and their contents and occupants.

A lightning protection system does not attract, repel, or prevent a lightning strike. Rather, it provides specified pathways on which lightning can travel, carrying the destructive power of the lightning strike safely into the ground.

A lightning protection system consists of numerous components that are constructed from highly-conductive copper or aluminum alloys, and that is where East Coast Lightning Equipment, Inc. comes in. We develop and manufacture UL-listed lightning protection components so installation specialists can effectively protect businesses and homes.

Elements of a Lightning Protection System

We have answered, what is lightning protection? Now it's time to take a look into the elements that make up a lightning protection system. A lightning protection system consists of five elements that work together to protect a structure from lightning damage. They are:

  • Strike termination devices such as air terminals (lightning rods),
  • Conductors (usually special braided metal cables),
  • Bonding connections (to connect metallic bodies within the structure)
  • Ground terminations
  • Surge protection devices.

To accomplish this, ECLE produces a variety of bases, connectors, fittings, and accessories to suit the full range of building conditions. It is imperative that each of these lightning protection system elements is properly designed and installed to ensure effective protection.

It is essential that lightning protection systems are installed by trained, qualified lightning protection specialists. All materials and methods should comply with nationally recognized safety standards for lightning protection as established by National Fire Protection Association, UL, and the Lightning Protection Institute. Lightning protection systems should also be designed with the aesthetics of a structure in mind, so components blend with the style of the building and are practically undetectable from the ground.


Lightning protection systems consist of a wide range of fittings, connectors and mounting hardware to accommodate the variety of construction materials used in today's buildings.

While lightning is a fact of life, lightning protection equipment from ECLE helps make buildings, businesses, and families safer from the devastating reality of a lightning strike.

frequently asked questions

Answers to common questions about lightning protection systems and lightning safety.

Yes. In fact, more lightning protection systems are installed now than ever before. Today’s lightning protection systems are inconspicuous. Since buildings today are equipped with many sensitive electronic systems, planners tend to include lightning protection systems not only to protect the structure but also to help protect the electronic systems that keep buildings up and running.

No. This common misconception dates back to Ben Franklin’s day. Lightning rods simply intercept a lightning strike and provide adequate pathways to safely conduct the lightning to the ground. If lightning is zeroed in on a particular location, it will strike that location, whether there is lightning protection in place or not. It is helpful to remember that lightning travels several miles to reach the earth. Tiny objects on the ground have no influence on controlling the path lightning takes through the air.

In most cases, unless you are looking for the lightning rods you can’t notice them. Lightning rods are typically just 12 inches tall and 3/8” in diameter. That’s not much bigger than a pencil. Placed on a roof that is 30–50 feet high and 18 inches in from the roof edge, the rods are barely visible from the ground.

There are a number of measures that can be taken to make lightning protection even less noticeable. There are different materials that can be chosen to blend with the architectural features, style, and materials. For instance, tin-plated copper can be chosen to blend with gray stonework, or copper blends well with dark materials.

When designed during construction all of the lightning protection systems, except the rooftop terminals, can be concealed and run inside the structure. There are also ways to avoid the use of air terminals, such as substituting thick-walled metal railings for the lightning rods. Decorative finials can also be used as air terminals, making the lightning protection an architectural accent.

Cost varies greatly depending on the location of the structure, its size, its construction, the complexity of the roof-line and the ground conditions. Costs are lower when the system is designed and installed during construction. Retrofitting a system, is very common, but tends to be slightly more expensive. In comparison with other building systems, such as security or plumbing, the lightning protection is usually less costly.

There are satellites that monitor lightning activity all over the world. This activity is charted and provides statistics that tell just how often lightning strikes any given area. At any given moment, there are 2000 thunderstorms happening somewhere in the world. The earth experiences 100 lightning flashes per second. The US alone has more than 40 million lightning strikes each year. Any given square mile in the US can expect approximately 40 strikes per year.

Some statistics regarding lightning damage include:

  • Between 1992 – 1996, it is estimated that 1.7 billion dollars were paid out by insurance companies in lightning related commercial claims.
  • The Insurance Information Institute reports that approximately 5% of all commercial claims are lightning related.
  • In 1996 a Federal judge upheld a judgment levied by OSHA against a Pennsylvania firm for failure to provide adequate lightning protection after two workers were killed by a lightning-caused explosion.
  • The US Fire Administration reported in 2002 that it estimates 17,400 structural fires are caused by lightning each year. Dollar losses per lightning fire are nearly twice that of fires started by other means.

Yes. The NFPA has maintained a standard for lightning protection for over 100 years. The standard is continually updated and edited to incorporate new findings. For example, in the last few years, sharp-tipped lightning rods have been replaced by blunt or round-tipped rods in NFPA requirements. This is the result of field research at New Mexico Tech that proved that blunt tipped rods are more successful in capturing a lightning discharge than a sharp tipped rod. The NFPA’s standard is based on the same practices and principles employed in recognized standards for lightning protection all over the world.

The FAA, NASA, Dept of Energy, and DoD typically do not build any structures without lightning protection systems. In fact, there was a federal report issued in 2004 that reviewed the technical validity of lightning protection and concluded that lightning protection systems are critical to protecting our national infrastructure. The American Meteorological Society issued a similar paper in early 2003.
