  • Patent number: 4479687
    Abstract: The invention provides an electrical distribution system comprising a length of conduit 10 containing a plurality of continuous conductors. Electrical access to the conductors is achieved via a contact plug and a series of spaced entry apertures which are shaped to receive the plug in a particular orientation. Safety door means are provided within the conduit for each aperture and are designed to prevent contact with the conductors by means other than the correct contact plug. In one embodiment of the invention, the conduit is in two parts comprising a support section for securing to a supporting surface, and a wall section containing the entry apertures.
