Panelboards

Electrical Supplies Unlimited (ESU) has more than 40 years of experience in the electrical supply business, providing electrical equipment to contractors, electricians, businesses, and industrial customers. We buy, sell, and maintain a large inventory of panelboards, including new, used, surplus, obsolete, and hard-to-find equipment. Our extensive inventory and experience allow us to help customers locate panelboards and related equipment for commercial, industrial, and electrical distribution applications.

Large Selection of Panelboards

ESU stocks a wide selection of panelboards and panelboard equipment in various sizes, configurations, voltage ratings, and amperage ratings. We specialize in helping customers locate specific panelboards and replacement equipment, including older and discontinued models that may no longer be readily available through conventional electrical supply channels. Whether you need equipment for a new installation, replacement project, or existing electrical system, ESU can help identify available options.

Major Panelboard Manufacturers

ESU handles panelboards from many of the industry's leading electrical manufacturers, including Square D, Siemens, Eaton/Cutler-Hammer, General Electric (GE), and ABB. We also handle panelboards and related equipment from other manufacturers. If you need a specific panelboard, provide the manufacturer, catalog or part number, voltage, amperage, and other available nameplate information so we can help identify the equipment.

Buy, Sell & Source Panelboards

ESU not only sells panelboards—we also buy new, used, surplus, and obsolete electrical equipment. If you have excess panelboards, unused inventory, discontinued equipment, or surplus electrical equipment from a completed project, contact ESU to see if we are interested in purchasing it. With more than four decades of experience and a large customer base, ESU can help customers source hard-to-find panelboards while helping businesses turn surplus electrical inventory into value.
