  • Switch/power drop unit for modular wiring system
    Patent number: 6777611
    Abstract: An assembly for connecting a pre-wired electrical device into a modular wiring system. The electrical device is mounted in a junction box having a knockout hole. Device wiring connects the electrical device through the knockout hole to a connector plug. Cable wiring connects a modular wiring system power tap connector to a connector socket. The cable wiring runs through a flexible conduit sheath. A knockout connector is connected to the flexible conduit sheath. The connector plug connects to the connector socket. The major width of the connector plug/socket combination is less than the diameter of the knockout hole such that the connector plug/socket combination may be pushed into the junction box through the knockout hole. The knockout connector can then be attached to the junction box at the knockout hole. The power tap connector housing, flexible conduit sheath, knockout connector and junction box are all made of nonflammable materials.
