WebDerating factor formula = Cable current * K1*K2*K3*K4…*Kn, While K’s are the derating factors of the cable. Total derating factors = K1*K2*K3 = 0.95*0.9*0.91 =0.77, Then multiply this value by the cable current. The resulted current should be the new current carrying capacity for the cable. Web20 apr. 2024 · IEC TS 62893-4-2:2024(E) applies to cables for DC charging according to mode 4 of IEC 61851-1.
