Panelboards are centralized electrical distribution systems that organize, protect, and control circuit branches. They distribute electricity to different areas in commercial, industrial, and residential buildings while ensuring protection against overcurrent conditions. Accessories include circuit breakers, busbars, trims, and mounting hardware that improve safety, functionality, and aesthetic organization. Panelboard interiors and trims safeguard internal components, while specialized panelboards serve unique power distribution needs. This integrated system simplifies electrical circuit management, facilitates quick maintenance, and enhances the overall protection and reliability of electrical systems, playing a crucial role in any well-structured power distribution network.
