IEC 60038 is an international standard that specifies the nominal voltages for electrical systems. It provides guidelines for the standardization of voltage levels used in various applications, ensuring compatibility and safety across different regions and equipment. This standard is crucial for manufacturers and engineers to design and implement electrical systems effectively. The standard covers a range of voltage levels, including low, medium, and high voltage categories. By establishing these nominal voltages, IEC 60038 helps facilitate international trade and cooperation in the electrical industry, promoting uniformity and reducing the risk of electrical hazards in installations worldwide.
