The present disclosure relates to a system and method for determining the electrical connections of a plurality of nodes. The nodes may include an electrical power distribution system including a plurality of nodes, connected to the power distribution system. At least two of the nodes include node electronics, at least one of the nodes is configured to be operatively coupled to an external power drawing load, and at least one of the nodes upstream from the node configured to be operatively coupled to the external power drawing load is configured to detect power drawn by the external power drawing load. The at least one upstream node is configured to send a node electrical signals using the node electronics indicating that the drawn power was detected. The system is configured to identify the wiring configuration of the plurality of nodes relative to each other based on the node electrical signal.
