A Feeder Box for Busway is the power entry unit at the starting point of a busway system. It is used to connect the busway to switchboards, circuit breakers, fuses, grounding devices, and other incoming power equipment. By providing a secure connection interface and centralized protection, the feeder box helps maintain stable and safe operation throughout the bus duct system.
In project applications, this unit may also be referred to as a bus duct tap box or a feed-in box, depending on the system design and installation method. Its main function is to introduce power into the busway while supporting protection, grounding, and system coordination.
