A 360° rotatable power grommet mounted in an aperture in a work surface, three vertical copper strips, each connected to a wire which passes through a base to connect to an electrical power source. The copper strips are mounted in a vertical shaft which connects to a base. There are one or more electrical receptacles having arms which rotate horizontally and close to form a central bore, the arms having inner surfaces which are molded with horizontal copper strips, the central bore clamping to the vertical shaft to transfer power from the vertical shaft to the horizontal copper strips, the central bore allowing each electrical receptacle to separately rotate 360° around the vertical shaft.
