Hi, The EN 300 386 (EMC requirements for telecommunication network equipment) require to perform a surge of 1.2/50 Tr/Th us, 0,5 kV to ports for indoor signal lines (in telecommunication centers), when cables longer than 10 m are connected ! Can some one explain my the rational of divided up to 10 m and more than 10 m, anyway all cable is in the building (indoors) ?
