Hi Peter, It would align with the guidance in IEC 61000-4-5 for applying surges to 'long distance lines and outdoor lines' which would include Ethernet leaving a building.
The built in voltage isolation of the Ethernet magnetics handles 1kV surges just fine. Main risk is a poorly implemented circuit with insufficient creepage or incorrectly rated components (I have seen both) Hope some of this ramble was useful James ---- Peter Tarver wrote ---- >Good morning. > >61368-1, Table 14 (2nd ed) or Table 13 (3rd ed) >discusses transients to be applied to conductors >considered external circuits. > >Whereas in 60950-1, these tests generally applied to >conductors falling under Clauses 6 or 7, the scope of >the applicability of the testing appears to have >expanded to include simple IEEE 802.3 circuits that >exit a building structure, which were excluded from >such testing under 60950-1 (where ITIC had dictated to >test houses, "thou shalt not place transients on mine >network circuits"). > >As a relative newcomer to 62368-1, I am looking for >confirmation that the above is accurate. > > >Regards, > >Peter Tarver >[email protected] > >- >---------------------------------------------------------------- >This message is from the IEEE Product Safety Engineering Society emc-pstc >discussion list.
