The standard Siemens switchboard frame is 90 inches high and 32 or 38 inches wide. An optional height of 70 inches with widths of 32, 38, or 46 inches is also available. A bus is a conductor or set of conductors that serves. Busbars are the backbone of a low-voltage switchboard: rigid conductors that collect and distribute current safely between incoming devices and outgoing feeders. In most assemblies you will find horizontal main bars, vertical risers, neutral and equipment-ground buses, and purpose-designed. Engineering use: Busbars are common in switchgear, panelboards, substations, busway, battery systems, and industrial power distribution equipment. They carry large currents and must be properly sized to ensure safety, performance, and compliance. A busbar is a metal bar, usually made of copper or aluminum, that carries electricity inside switchgear.
