Road vehicle wires (ISO 6722, LV 112, SAE J1128, JASO D611): how to read the cable type names
Each name in Road vehicle wires (ISO 6722, LV 112, SAE J1128, JASO D611) stands for a whole cable type: FLRY, for example, comes with its own construction, standard and rating. The decoder knows 17 types of this system. Below: how the names are built, every type with its rating, and the sources the table names.
