Abstract: Method (200) for automatically re-phasing the current of a domestic electrical network or similar, through an automatic electrical re-phasing apparatus comprising the steps of:—comparing (202) for a first portion of a set execution time period, through a central processing unit (10) of such an electrical re-phasing apparatus, electrical operating parameters detected by the electrical network with respective preset electrical reference operating parameters, said step of comparing (202) comprising a step of calculating (205) through the central processing unit a phase shift representative of the power factor;—sampling (209), through the central processing unit, in the said first portion of time, such electrical operating parameters detected by the electrical network and the calculated phase shift; calculating (210), through the processing unit, in the said first portion of time, a correction value of the calculated phase shift; controlling (211), through the central processing unit, in a second portion of the s
