Which grounding kit to choose?

 

The range of grounding tasks is huge. Grounding is required for private houses, workshops, industrial enterprises, special equipment, etc. The choice of a grounding device is determined by the requirements of regulatory documents and regulations for the operation of grounded equipment, the nature of the soil, the place reserved for the organization of grounding and other factors

Having extensive experience in solving grounding problems, we have developed several grounding kits that facilitate the design and implementation of grounding devices. Each kit contains a passport instruction and a set of products (copper-bonded rods, couplings, tips, etc.), which allows you to organize a grounding device with a service life of more than 30 years. The composition of the kit, the recommended configuration of the grounding switch and the expected resistance values of the mounted kits are presented in the table below.

How to choose a grounding kit?

 

ZANDZ ZZ-000-015 kit is a typical solution for creating high-quality grounding for single-family houses with a gas water boiler and administrative / industrial buildings located in the middle latitudes of Russia (taking into account the most common type of soil). ZANDZ ZZ-000-030, ZZ-000-045, ZZ-000-424 and ZZ-000-636 kits allow you to achieve the required grounding characteristics in conditions other than ordinary.

The grounding kit for a single-family house ZANDZ ZZ-6 is specially designed for self-installation. An important feature of the kit is the application of the technology of the clutchless connection of ground rods and the absence of need to use electric tools during installation. To install the kit you will need a sledgehammer and 2 wrenches. 

To connect the grounding or to connect the grounding conductors to each other, grounding conductors may be required, which are purchased optionally. To connect grounding conductors in the ground, it is recommended to use a steel copper-bonded tape of 30 * 4 mm in coils of 10, 20 and 50 meters and steel copper-bonded wire with a diameter of 10 mm and in coils of 10, 20 and 50 meters. To connect the grounding device to the grounding object (for example, the grounding bus, the grounding terminal of the equipment) - a copper wire in PVC insulation with a cross section of 25 mm2, 3, 5, 10 and 20 meters long, with a tip for a bolt with a diameter of 8 mm.

Installation of modular grounding is possible not only outside the boundaries of the building, but also inside the buildings. Basement or ground floor are perfect for placing a grounding device.

Upon your request, the specialists of the ZANDZ Technical Center will calculate and select materials for free to solve non-ordinary or requiring special treatment grounding tasks.
