A method for assigning individual phase conductors at a first point to those at at least one further point in a polyphase energy distribution network, in particular in a three-phase network. In the case of mains operation, wherein a common reference time is determined for these points, and the time difference and/or phase difference of the phase voltage or the line-to-line voltage between the reference time of a zero crossing of the phase voltage are determined for these points. By a comparison of the time and/or phase differences at two different points the phase conductor of one point is assigned to a phase conductor of the further point which has the same to time and/or phase difference with respect to the common reference time. An additional loading of the energy supply network or an interruption of the mains operation is avoided by the method.
