  • 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.
