I am having a 42KW 3 phase electrical heating furnace, heating element is 80/20 nichrome material, my connections is made in such a way that 2 star connection compromising 2 coils per phase so totally 12 coils, shall if i use it unbalanced star condition (instead of 2 group of 3 phase or 1 group of 3 phase, connecting 4 phases of 5 phases) what will be the consequences and is it acceptable?
