The generac 8 KW generator i'm wiring comews with a 30 ft line from transfer panel to outdoor box of the generator. Unfortunly, I still need maybe another 6+ ft. Because the 70 amp (#4 copp) conductors are thhn, to extend line; must I use also thhn conductors for the control wires. i'm not sure if those any of those 16 GU wires are 120/240 V, and cant find markings on them except there designation(n1,n2 ect). I have TFFN wire stranded, and not sure if that could be a problem if used.
