Abstract: A connection device with circuit integrity in case of fire where the connection device is configured for tapping into a flat cable without stripping an insulation where the flat cable is configured with plural high power current strands extending parallel and offset from one another in a plane, wherein the connecting device reaches about the flat cable and includes contact screws that are configured to be screwed into the flat cable, where a respective pair of contact screws is provided for the respective high power current strands, wherein the two contact screws of a pair are arranged so that one contact screw contacts one side of a conductor of the high power current strand and another contact screw contacts another side of the conductor of the high power current strand when the flat cable is connected, wherein the contact screws respectively include threads so that the conductor is laterally clamped by the two contact screws with the threads.

Abstract: A flat cable deflection device with circuit integrity in case of a fire including a cylindrical cable deflection element made from fire resistant insulating material; and a support for the cylindrical cable deflection element made from fire resistant material. The support is offset from the cylindrical cable deflection element so that the support facilitates enveloping the cylindrical cable deflection element with a flat cable without the support contacting the flat cable. An electrical installation including at least one flat cable deflection device; at least one flat cable including plural high power current strands extending parallel adjacent to one another in a plane, where the flat cable runs over the deflection device and changes its direction at the deflection device, wherein the transversal cable direction in front and after the deflection device extends horizontally, and wherein the flat cable envelops the cylindrical cable deflection element at least partially.

Abstract: An electrical low voltage building installation, wherein excess current protection devices are provided for conductor branch offs with cross-section reductions, wherein at least one distributor conductor is provided at which conductor branch offs for branch conductors with a reduced cross-section compared to the distributor conductor are arranged in the building in a distributed manner, wherein the associated excess current protection devices are arranged accordingly distributed at the conductor branch offs or subsequent to the conductor branch offs in the branch conductors, wherein the excess current protection devices that are arranged in a distributed manner are configured to be switched on again through remote control after triggering, and wherein the excess current protection devices do not require a remote control function for interrupting their respective conductor branch off or branch conductor, but perform the interrupting locally, this means upon their own determination of an excess current.
