The invention relates to a network infrastructure component and a distributed network system for supply purposes comprising a plurality of network infrastructure components, wherein the network infrastructure component comprises at least one contact unit for connection to a further network infrastructure component, and at least one coupling module for coupling a functional group, wherein the network infrastructure component is designed to communicate with a coupled functional group at least at a supply level, wherein the network infrastructure component is designed to communicate with at least one further network infrastructure component at least at the supply level and/or a data level, such that a self-configured network system for linking a plurality of functional groups can be produced with a network of a plurality of network infrastructure components. Preferably, the network infrastructure component comprises a control device for controlling operating parameters, in particular for load control at the supp
