Busbar
Busways, or bus ducts, are long busbars with protective covers. Rather than branching from the main supply at one location, they allow new circuits to branch off anywhere along the busway.
What is a bus bar panel?
The purpose of a busbar is to consolidate and distribute electrical power efficiently within a panel, providing a robust, low-impedance path for high currents and simplifying connections to
