The present invention provides a support system for supporting the commissioning of a networked power distribution system (1). The networked power distribution system comprises at least one power supply (2) with one or more power connectors (12, 12a) for supplying power to the one or more power connectors and a data communication interface for exchanging communication data. The support system (6) comprises one or more load device detectors (7) for detecting the connecting and/or disconnecting of a load device (3a) to/from a power connector (12a), and a commissioning tool (8) for performing steps of commissioning the networked power distribution system with regard to the load device. The commissioning tool is adapted to automatically perform at least some of the commissioning steps in response to the detection of the connecting and/or disconnecting of the load device. This can allow for a relatively easy commissioning of the networked power distribution system.
