A management method for managing an electrical installation comprising several electrical elements (16A, 16B, 16C) in order to circulate a current from a point of origin to a point of electrical power distribution, each element comprising a first memory means for storing a first unique identifier associated with said element (16A, 16B, 16C), the method comprising the following step: - a) acquiring, via an identification means, the first identifier of each element (16A, 16B, 16C) belonging to the installation, characterized in that each first memory means is also capable of saving geometric data of the corresponding element, said data being acquired during the acquisition step a), via the identification means, and associated with the corresponding first identifier, and in that the method further comprises the following step: - b) computing, via a processor, a model of the electrical installation based on the acquired geometric data, the elements comprising at least one electrical power distribution element, each distribution element having a predetermined number of electrical tap off outlets capable of each being connected to an electrical tap off box, wherein each corresponding first memory means comprises said number of tap off outlets, and wherein for each electrical power distribution element, the computation of the model is performed based on the acquired number of tap off outlets, each element (16A, 16B, 16C) comprising at least two connection ends (29, 30), the geometric data comprising the positions of the connection ends (29, 30) of the corresponding element (16A, 16B, 16C), in a coordinate system associated with the electrical installation, after the computation step b), the method comprising the following steps: - c) measuring, by each electrical tap off box, one or more electrical properties relative to the electrical installation, - d) transmitting the measured property or properties to the computing member, - e) associating, within the model, the measured electrical properties with the corresponding electrical tap off box and with its position in the electrical installation, the method further comprising, when one of the electrical properties is above a reference threshold, an indication to an operator of the location of an electrical fault of the faulty electrical element (16A, 16B, 16C). -
