As a power wiring method, a wiring method using a wire cable is common, but as a wiring method in a high-rise building or a large factory, a wiring method using a bus duct having a bus bar is adopted.

Booth ducts and cables have a common point in that they have conductors and insulators, but compared to cables, cables use vinyl or rubber to protect or insulate conductors, but booth ducts carry high-voltage current through the conductors. Therefore, it is difficult to protect directly as an insulator, so that the insulator is covered with the busbar of the bus duct, and the bus bar is embedded in the metal duct, thereby protecting the conductors and insulators constituting the busbar. It is easy to deal with accidents at the time and it is easy to manage the system.

In the case of installing such a booth duct, the length of the booth duct may be longer or shorter than the preset installation length due to a manufacturing error or a construction error. The unit was installed and used.
