The safest place to stay during a lighting storm is indoors. A home or substantial structure like office building is the best protection from lighting strike. No residential home is immune to the threat of lighting strike damage. To ensure your home is protected, you should consider residential lightning protection. Install lighting protection system with these essential parts.
A home structure that has a high probability of lightning strikes needs an air terminal as its function is to capture the strike. Based on the size and shape of the structure, keep these design rules in your mind:
- Extend terminals to at least 10 inches above the roof line
- Place the air terminals on roof projections like chimneys
- Brace air terminal that’s greater than 24 inches in height
- Install air terminals within 2 feet of a roof ridge or within 2 feet of outside edges or corners on flat roofs
Electrical Equipment Protection
Direct lighting to your home’s exterior can be really catastrophic and can damage electrical equipment as well.
A strike that is several hundred feet away can also trigger a power surge to telephone lines or electric or other conductive lines such as satellite dishes or cable TV. So, install a hardwire surge protector on the electrical panel in order to protect the electrical equipment within the home.
A conductor works together with an air terminal and redirect the electrical path of a lighting strike to the ground rather than to the structure. Follow these installation tips on a residential home:
- There should be at least two conductor paths which leads to the path from each air terminal.
- Install down the conductors from the roof to the ground level at opposite needs of the home. Don’t install less than two conductors
- Bond metallic rooftop objects such as vents or gutters to the conductor system
- If you choose the right conductor, understand the product may be aluminum or copper. You should also check whether the conductor is UL listed for its application.
Grounding system is essential at a residential home for lighting strike to be discharged into the ground. It includes a copper bonded ground rod that’s installed in the ground. Follow these requirements while installing lighting protection grounding system at your home
- Copper bonded electrodes are recommended
- Ground electrodes should be one-inch in diameter by 8 feet long
- The grounding system should be interconnected by using the same size conductor
- If underground service lines or rocky soil prohibit the use of vertical electrodes, then a horizontal conductor is needed. At least it should be buried 18 inches below the ground and extend not less than twelve feet away from your home
- Interconnecting bonds are required for underground metallic piping systems such as gas or water pipes within 25 feet of your home
- If all the services were already bonded before the lighting protection installation, its required to bond the nearest lighting protection ground electrode to the water pipe system
