维基是这么给介绍的：
Modern industrial switchboards are metal enclosed and of "dead front" construction; no energized parts are accessible when the covers and panels are closed. Previously, open switchboards were made with switches and other devices were mounted on panels made of slate, granite, or ebony asbestos board. The metal enclosure of the switchboard is bonded to earth ground for protection of personnel. Large switchboards may be free-standing floor-mounted enclosures with provision for incoming connections at either the top or bottom of the enclosure. A switchboard may have incoming bus bars or bus duct for the source connection, and also for large circuits fed from the board. A switchboard may include a metering or co***ol compartment separated from the power distribution conductors.
现代工业配电盘是金属封闭型和“板前操作型”; 当盖子和面板关闭时，没有通电部件可以触碰。 以前，开放型的配电板由开关及其他装置安装由花岗岩或乌木石板制成的面板上。 配电板的金属外壳接地，保护人员。 大型配电板是自立式立地安装的结构，其可以在外壳的顶部或底部提供输入连接。 配电板也可以是那种由母汇流排连接的或汇流总线管道式电源接入的机构形式，或者由馈电开关输入电源的机构形式。 配电板可以包括与配电导体分离的计量或控制室。
