Electrical equipment supplies power to facilities and work projects. Electrical products and power management supplies can be used to run equipment and install electrical systems into buildings. Wires, fittings, and switches are necessary for making repairs to electrical systems. Circuit breakers, push buttons, and other electrical parts can be used to create electrical components. Conduit and strut channels organize, route, and protect wire and cable. Portable power supplies keep job sites up and running when wired electricity is not available. Voice and data equipment includes cables, patch cords, and jacks to facilitate the transmission of signals. Cabinets and racks store equipment and keep wires and cables organized and stowed away.
