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?
can anyone explain the star-delta motor control wiring ,which wire go where and how they operate?

In our plant we have installed new MCC with ELR and CBCT which is detecting some leakage current in the system but it leading to some confusion when to check that in which feeder which is drawing current we put off the whole panel itself but still CBCT detecting some leakage current so can anybody ans me , where i am going wrong or how to detect whether its actual leakage or CBCT malfunctioning.
