Dear experts, What are your experiences about protective earthing terminal according IEC 62368-1?
Unit provides 2 earthing terminals. One as a stud/bolt directly on the enclosure. This provides reliable connection to PE and fulfils all requirements of the standard. Second one on the input terminal. Do both connection need to comply with protective earthing terminal requirements if both are marked with protective earthing symbols and they both need to be connected? Problem is that second connection has a wire from PE terminal to enclosure with cross-section of 5,2mm2 (AWG10). According to table 31 of IEC 62368-1:2018, 6mm2 is required for 63A and 4mm2 is required for 40A. Rated current of the unit is 47A. There is no note in the table that linear interpollation is allowed. Any idea? Thank you.
