When organizing the work of any type of electrical equipment, the main requirements are always reliability and safety. Only a properly debugged electrical network can work efficiently and efficiently. The ground bus is the most important component of the electrical network, the purpose of which is to ensure a high level of safety when working with a variety of devices. First of all, such a conductor is used to enter ground loops from various conductive elements of the switchboard, as well as to organize external security.
The device is called a grounding device because it brings out a chain of conductive wires from all parts of the electrical cabinet and appliances installed in it.
A conventional ground bus, or, in other words, a zero bus, is usually installed on the chassis of wiring cabinets, and it is to it that electrical equipment cases will be connected in the future.
The conductor is placed vertically on the sides of the electrical cabinet andfastened with several bolts.
After installation, all grounding devices must be painted purple.
The ground bus can be installed either in those places that only specially trained personnel have access to (in this case, it can be placed openly), or in those areas that unauthorized persons have access to (then it should be protect with a special shell). Ideally, it should be installed in a drawer or cabinet that can be locked.
Grounding of various electrical appliances and devices is carried out according to the state standard, which implies the use of two types of grounding bars: model REC-ET2-M and model REC-ET. The first type is fastened directly to the mounting profiles of electrical cabinets and racks and provides for the possibility of connecting 16 or more circuits, and the second type ground bus requires the use of a special organizer, with which up to 9 wires will subsequently be connected and installed.
If we talk about the materials from which this conductor can be made, then copper has received the greatest distribution and application. It is from this material, which does not contain any impurities, that the safest ground bus is obtained. The copper base allows you to provide one hundred percent protection against the consequences of a possible short circuit and helps to completely eliminate the negative effect of atmospheric and static electricity. For hercharacterized by high thermal conductivity, excellent electrical conductivity, small resistivity, hardness, density and corrosion resistance. The standard cross section of such a conductor is 3 by 20 mm.
Copper grounding bars are important to use for the installation of electrical cabinets, various technological equipment, ventilation ducts, etc. These devices are perfect for both indoor and outdoor use.
