    • An electrical outlet raceway that eliminates the necessity of daisy chaining or doubling of electrical cords within the raceway. The electrical outlet raceway includes a modular system of several components that can be assembled together in order to provide additional electrical outlets on a wall, including a raceway back plate, a cordless receptacle, a raceway cover, a coupler, and one or more faceplates for attaching a high or low voltage component to the raceway. The electrical outlet raceway may also include a corner, end caps, and means for attaching faceplates to the raceway. Cordless receptacles enable the use of off-the-shelf electrical cords, thus allowing the installer to plan a given installation and obtain the proper number and lengths of electrical cords required to construct the planned installation. This eliminates the inefficiencies caused by the corded receptacles of conventional electrical raceways.
