European cable branch boxes are widely used in cable engineering equipment in power distribution systems in recent years. Its main features are two-way door opening and wall-through bushing as a connecting busbar. They have significant advantages such as small length, clear cable arrangement, and three-core cables do not need large span crossing. The cable connectors it uses comply with DIN47636 standards. Generally, rated current 630A bolted connecting cable connectors are used.
American cable branch box is a cable engineering equipment widely used in power distribution systems in North America. It is characterized by one-way door opening and transverse multi-pass busbars, and 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 600A main circuit and 200A branch circuit. The 600A main circuit adopts screw-in bolt-fixed connection; the 200A branch circuit adopts plug-in connection, and can be plug-in with load. The cable connectors used in American cable branch boxes comply with IEEE 386 standards.
