                                                  Lightning is a phenomenon that generates a high frequency voltage:

                                                  • The length of the cables must be taken into account in cases of high frequency
                                                  • 1 metre of cable crossed by a lightning current generates an overvoltage of 1,000V
                                                   
                                                   
                                                   
                                                   
                                                   
                                                   

                                                   

                                                   
                                                   

                                                  Mandatory in Standard IEC 60364-5-534:

                                                  • L (length of cables) < 50cm,
                                                  • cable cross-section S < 4mm²(Type 2) and S< 16mm² (Type 1).
