In accordance with


            ISO 10133 Third Edition 2012-12-15:



            “7.11 All D.C. negative conductors
            shall be identified by black or yellow
            insulation. If the craft is equipped
            with an A.C electrical system, yellow insulation shall be used for D.C negative conductors
            of the D.C. system”


            In small craft with mixed A.C. & D.C. environments,
                D.C. negative conductors must use yellow insulation.






                Positive ( + )                                       Negative ( - )











            Note 1:
            In accordance with IEC 60446, conductor insulator colours of the A.C. system are:
               - Live conductors: black or brown;
               - Neutral conductors: white or light blue;
               - Protective conductors: green or green with a yellow stripe



            In small craft with only D.C. environments,
                D.C. negative conductors may use yellow insulation or black insulation.
