Refere to the table to determine the maximum allowable cable length, as to size and motor ratings. The table referes to H07RNF cables with insulation suitable for operating temperature of the conductor up to 60°C. For 415 V the maximum admitted length of the drop cable increase by 10% as per the value marked in the table. For 415 V the maximum admitted length of the drop cable increase by 10% as per the value marked in the table.
