Typically, this is lightning , grounding device and collector . As lightning receiver using any taper pin , or is made of a durable metallic alloy.

The internal system is to use a bit of electricity networks of devices intended to limit the voltage level .

Internal system to protect homes against changes in electricity can not be fully executed independently . But having certain skills with electric cables and electrical appliances can be integrated to self- ready devices to the network.

Lightning protection metal roof during repairs

Of strips of metal make earthing . Its cross section must be at least 150kv.mm . For these , you can use more whole rod of steel. Since about the 18 mm diameter .

All components are connected by electric or metal clamps that attach to the nuts and bolts .

Grounding system do not far from home , 1.5 meters . Which height ground will be located entirely dependent upon in which position the protection angle equals 70 °.
