Recommended maximum cross section of connected cables according to IEC 60947-7-2 and IEC 60947-7-1 : Type A : 8 AWG copper ( tested permanent current = 57 A ) Type B : 2 AWG copper ( tested permanent current = 125 A ) 4 / 0 AWG copper ( tested permanent current = 269 A )
Fastening of thicker cable is acceptable , if the maximum allowable permanent current is not exceeded and the provisions on cable lug thickness are observed .
