Abstract: An electrical panelboard having stacked elongated, flatwise aligned, flat bus bars and plug-in load-side connectors is provided with a mounting pan formed of flat, edgewise aligned extruded aluminum bars extending parallel to the bus bars in spaced relationship thereto edgewise thereof. Electric circuit breakers for use on the panelboard are provided with plug-on line terminal jaws for plugging on the bus bars and stab load terminals for plugging into the load-side connectors by movement of the circuit breakers parallel to the mounting pan toward the bus bars. Various combinations of two types of extruded bars are used to accommodate four different sizes of plug-in load-side connectors. The bars are longitudinally grooved to receive mounting screws for the plug-in load-side connectors anywhere along their length. Panelboards of various widths respectively accommodating circuit breakers of various sizes may be constructed by mounting various numbers of the grooved bars parallel to and at various distances respectively from each of a plurality of bus bar stacks.

Abstract translation: 具有堆叠的细长，平坦对齐的扁平汇流条和插入式负载侧连接器的电板具有安装盘，该安装盘由平行的沿边对齐的挤压铝棒形成，平行于汇流条与母线横向延伸。 在电路板上使用的电气断路器设有插入式线路端子爪，用于插入母线和刺穿负载端子，以便将平行于安装盘的断路器移向母线插入负载侧连接器 。 两种类型的挤压棒的各种组合用于容纳四种不同尺寸的插入式负载侧连接器。 这些杆纵向开槽，以便在其长度的任何地方接收用于插入式负载侧连接器的安装螺钉。 各种尺寸的各种宽度的断路器的面板可以通过将各种数量的带槽条分别与多个汇流条组合中的每一个平行并以各种距离分别来构造。
