The difference between European-style cable branch boxes and American-style cable branch boxes:
European-style cable branch box is a cable-based engineering equipment that has been widely used in power distribution network systems in recent years. Its main features are two-way opening doors and the use of wall bushings as connecting busbars. It has significant advantages such as small length, clear cable arrangement, and three-core cables do not require large-span crossovers. The cable connector used complies with DIN47636 standard. Generally, bolt-fixed cable joints with a rated current of 630A are used.
American-style cable branch box is a kind of cable engineering equipment widely used in power distribution network systems in North America. It has one-way door opening and horizontal multi-pass busbar as its main features. It has significant advantages such as small width, flexible combination, full insulation, and full sealing. According to the rated current, it can generally be divided into two types: 600A main circuit and 200A branch circuit. The 600A main circuit adopts screw-in bolt connection; the 200A branch circuit adopts plug-in connection and can be plugged in and out under load. The cable connectors used in American-style cable branch boxes comply with IEEE 386 standards.
