  • Installation system
    Patent number: 5430251
    Abstract: An electrical junction box has conductor sections in the form of contact rails inside the box. The box has sides with openings for passing power lines. Replaceable conducting strip holders hold the contact rails within recesses in the base of the box. Covers over the conducting strip holders have openings so that the contact rails are accessible from inside the box.

  • Electrical energy distribution system
    Patent number: 5383090
    Abstract: A modular electrical-energy distribution system has at least one conductor and a contacting device which makes it possible to establish, at essentially any point in the conductor system, a contact with the conductor. The tap or contacting devices essentially clamp onto or between conductor bars and therefore essentially permit all contacts to be made simply from one side of the conductor bars thereby reducing installation time.

  • Electrical installation system
    Patent number: 5326933
    Abstract: An installation system for wiring of a building has at least one junction boxes connected together, with each junction box having a removable plug-in block disposed at the back thereof. The plug-in block has conductors therein with sockets for providing access to the conductors, so that essentially all of the necessary electrical connections needed for wiring the building can, by means of the sockets and corresponding plugs on the power lines and electrical accessories, be made by simply plugging together the plugs and the sockets.
