Abstract
System of current protection of a primary electrical distribution box supplied by at least one electrical energy generator and delivering electrical energy to at least one load and/or to at least one secondary distribution box, comprising a line contactor for each generator arranged between the primary electrical distribution box and said generator, the primary electrical distribution box comprising an electrically conductive frame. The system of protection comprises an electrical connection member capable of electrically coupling the frame of the box to an external metal structure coupled to the earth, a current sensor capable of measuring a current flowing through said electrical connection member, and control means capable of controlling the line contactors so as to electrically decouple at least one generator from the primary electrical distribution box if a current flowing through said electrical connection member is detected.
