That receptacle also makes and breaks the electrical contacts responsible for feeding the luminaire. The load-bearing portion of this new component, called the mounting support, is installed in the ceiling box and includes the energized receptacle contacts that will feed the lighting fixture or ceiling fan. An attachment fitting that connects to the mounting support and the energized contacts built into that support is incorporated into the design of the lighting fixture or fan. The fixture or fan attaches to the mounting support with a twist lock motion. These new attachment fittings can save valuable time when installing lighting outlets.
