<p>A switchboard construction utilizes modular, insulative mounting panels to both electrically isolate and physically mount the various busbars, as well as, via line straps, the various electrical devices to the cabinet frame. The mounting panels installed vertically end-to-end also serve as rear barriers for the compartments accommodating the electrical devices. Barrier sheets secured to the front and back of the panels shield personnel from live parts. Load straps pass through apertures in the panels and vertical buses to the rear of the cabinet for convenient load connection. Horizontal bus sections are joined, electrically connected to and mounted by the vertical buses at common locations.</p> |
