Lightning rod system for metal roofing is divided into external and internal. External system is needed to protect the house from lightning and internal system - to protect electrical surge. The principle of operation of the grounding system is quite simple. Lightning, getting to the top of the grounding switch, passes in the ground through the lightning arrester and through it goes deep into the ground. To set the internal grounding of the metal roofing itself is very difficult, we need a specialist or purchasing of the ready-made system. The external grounding process is easier, but also better to entrust it to the professionals.

How to install the external grounding of the metal roofing

At first you should make the pantograph. It may be ordinary wire having a circular cross section. The pantograph is connected to the rod-type lightning arrester. The lighting arrester is a connector between the grounding and the pantograph. The grounding switch is made of a thick section of at least 15 square centimeters. Further, all connected by welding or clamps. Grounding of the metal roofing is done at a distance of a meter or more from the house. Corner of protection should be about 70 degrees with respect to the pantograph.

How to make the grounding of the metal roofing more effective?

Please pay your attention that the highest point of the pantograph should be done in the form of a cone. Just to be sure, you can install multiple pantographs with one grounding.

For more accurate setting of the pantograph you should be familiar with the following nuances:

- The objects, which are located at a high altitude, attract lightning, not only over the top, but with more peripheral sides of the thundercloud.
- The most effective pantographs are made of rope objects.
- Using the grid does not give more guarantees of protection.
