How to install a lightning rodPeople living in private homes, fear of falling into their home lightning. Some of them in order to protect themselves from this thinking about the protection of the structure. Their concern is understandable, since there are regions where the intensity of lightning in a year can reach up to 80 hours. In such a locality it is necessary to install lightning rods. The device of such a construction, of course, requires a certain cost. However, in some cases they can be minimized if all the work on the creation of a lightning conductor to do their own hands.

Protection zone

Ways to create a lightning rodIt should be understood that any structures designed to protect against lightning have a limited range. They only protect the space around them. Therefore, when creating a lightning rod construction, it is necessary to perform work so that all objects located on the site fall into the protection zone. Only in this case they will be protected from lightning.

At the moment, by the degree of reliability distinguish structures that protect against lightning. There are two types of them:

  • type A;
  • type B.

Lightning rods of the first type provide 99% protection, which makes it possible to call them the most reliable anti-lightning designs. Buildings of the second type provides 95% protection.


What are the elements of the lightning rodIf you are seriously afraid of lightning entering your home and, in order to protect yourself from this, you have decided to arrange a lightning conductor, then in this case during the work you will need to create the following items of this structure:

  • interception rod;
  • current lead;
  • grounding

Lightning rod

Creating a lightning rod in a private houseThis device, which looks like a metal rod. After installation, it will rise above the roof of the building. It will fall on lightning strikes. Thus, reliable protection of the structure is provided. In addition, such a device is able to withstand severe stress loads that occur when lightning strikes. When creating this item, you can use different materials.

The best choice - strip steel or round steel, whose cross-sectional area is not less than 60 square meters. m. This element has certain requirements in terms of length. This parameter should be at least 20 cm. The fixture should be placed strictly upright. The tallest building on the site is the perfect place to secure it.

Current lead

How to make a lightning rod in a private house with your own handsThe current lead has the form of a thick wire, whose diameter is 6 millimeters. To create it, galvanized steel is the best choice. With regards to its location, it is better to choose the areas in which lightning is most likely. For example, a gable edge can be a good place to place it. It can also be placed on the ridge. The fastening of this element of the lightning rod is made close to the private house, but with a small indent of 20 cm.

If the house has a roof made of materials that are easily flammable, then in this case the gap is all the more necessary. To secure the current lead need to use special fasteners: nails and staples. For greater reliability of fastening of this element, you can use clamps.

Earthing switch

Lightning rod in a private house does not prevent the occurrence of lightning, it only removes it, protecting the house from fireIt is necessary to divert the current from the lightning to the ground. When choosing a material to create this lightning rod element, it is necessary to use one that conducts an electric charge well. It is also necessary that the material has minimal resistance. If we talk about its location, then place this element of the lightning rod near the porch of a private house, not less than 5 m. It is recommended to install a grounding conductor in the immediate vicinity of the tracks, as well as in places where people may be located. After its placement, in order to make sure that it does not cause harm, you can create a fence around it.

When constructing a fence from the grounding conductor, it is necessary to indent 4 meters, and arrange the fence itself along the radius. If the weather is good, it will not do any harm. But if it is overcast, and even more so a thunderstorm has started, then standing in close proximity to it can be dangerous to health. Install earthing is in the ground. The decision on the amount of penetration of this element is made by the owner of the house. The following points should be taken into account:

  • soil type;
  • availability of groundwater.

For example, if the land is dominated by dry soil and the groundwater level is low, arrange a grounding switch consisting of two rods. The length of each of them should not exceed 3 meters. The components of this element need to be fixed on the jumper, whose cross-sectional area should be 100 square meters. m

When this is done, the grounding conductor is fixed to the current lead by welding. After that, it sinks into the ground at a depth of 0.5 meters. In that case, if the soil is peaty and has high humidity, and groundwater is located close to the surface, then there is no possibility of grounding for half a meter. Therefore, in this case metal corners must be usedthat will act as a ground. They are immersed to a depth of 80 cm.

DIY lightning rod

How to install a lightning rod-tower for a country house - the device and the order of workIf a multi-storey building is being built, then in this case specialists will carry out work on the installation of a lightning rod. These structures have their radius of protection zonethat makes it possible to place them on each building. Before installing this structure, they check whether the installed lightning rods are capable of providing protection against lightning of the erected building or whether it is necessary to erect a new one.

In the case of individual houses, the owner decides the issue with the lightning conductor. There are a number of factors in the placement of buildings that minimize the risk of lightning entering a house:

  • if the house is located in the lowest place on the plot, the probability of lightning falling into it during a thunderstorm is small;
  • if a building with a large height is located next to the dwelling, then a lightning bolt is more likely to hit it. This way your home will be safe;
  • if a lightning rod is installed on the neighboring house, then its protective coverage area may extend to your home. And in this case there is no great need for a lightning conductor device.

Thus, it cannot be said that a house without a lightning conductor is subject to a high risk of lightning.

Options for creating a lightning rod

How to protect yourself and your house from lightningIf you conducted an inspection of your and neighboring houses and as a result, you found that on nearby buildings such there is no protection, as there is no lightning conductor, in this case the most reasonable thing is to carry out work on its creation with its own by hands. Of particular danger are buildings whose roofs are covered with metal tiles or sheets of steel. Although such a roof looks attractive, the lack of grounding increases the risk of lightning getting into such a house.

In most cases, the installation of this roofing is made on the batten, which is made of wood. This provides an accumulation of charge. The discharge of such a device can occur only after a thunderstorm. A person who touches it can receive a current discharge of several thousand volts. In addition, do not forget that a spark may occur after a lightning strikefrom which a wooden house can easily ignite.

If you want to avoid such unpleasant situations, then need to think about groundingwhich should be located every 20 cm. If your home has a metal roof, then in this case you can refuse to create a lightning conductor. The roofing material itself will be an excellent lightning receiver.

Tree as a lightning rod

Lightning rod - a device to protect buildings and structures from lightning strikesTo save your home from lightning discharges, you can install a lightning conductor on its roof. However, other options are possible. If there is a tall tree near your dwelling, then you can install a lightning rod with your own hands, but provided that it is located at a distance of three meters from the building, and its height is 2.5 times greater than that of your houses.

If such a lightning rod option seemed attractive to you and you decided to arrange it, then you would need a 5 mm wire. You should first prepare it, then bury one end in the ground, pre-weld it to the ground. The other end will act as a lightning receiver. It must be placed at the very top of the tree.

In the event that there is no tall tree in your area, you can use an air receiver mast with two metal rods instead. They are installed at opposite ends of the roof. The drain in this case will act as a current lead. Of great importance is the material of its manufacture. It must be metal. In this case you should not forget about the device of the grounding conductor.


Regardless of which method you chose to install a lightning rod, you need to remember that by completing the installation of this design, you will ensure yourself a comfortable stay in your wooden house. But it is necessary to periodically check the condition of the lightning rodmade by hand. Special attention must be paid to its compounds. Violations in them must be absent. Only in this case, you can not be afraid of falling into the house.
