The invention involves a busbar distributor for electrical energy, and uses at least one consumer terminal (CT) for at least one consumer for supplying the consumer with electrical energy, as well as at least one connecting element for connecting a building energy supply (BES) to at least one high-voltage busbar, which connecting element connects the consumer to the BES. The distributor further has at least one line element which is provided between the connecting element and the CT, and a connector which is arranged between the CT and the connecting element. The connecting element has at least two conductors for supplying power to the CT. Also, the connector is connected, on an energy supply side, to the line element, which is formed having two conductors for energy supply which can be connected to the BES. The line element is exchangeable depending on the actual voltage and/or the power system of the building energy supply.
