FIELD: electricity.
SUBSTANCE: invention relates to the field of electrical installations used for the purpose of electric energy production, conversion and distribution, containing metal structural parts with metal coating. Electrical installation part connection assembly includes connecting metal parts and metal fasteners, fastening the said parts to each other with provision of electrical connection, wherein the said connecting parts and fastening elements are provided with metal coatings, made of metals having lower electrode potentials than the metals, from which the said connecting parts and fasteners bodies are made. In the assembly a sacrificial metal part on its surface containing a metal having a smaller electrode potential than the metals from which the metal coatings of said connecting parts and fastening elements are made is additionally included.
EFFECT: enabling increase in the electrical installations connecting parts electrical potentials equalization reliability in the electrical equipment components parts connection units, as a result of increase in the connecting parts with metal coatings to the fastening elements metal coatings electrical contact maintaining reliability.
