How do you usually connect three single phase loads to a three phase electric generator?:)

My best shot: A-B, B-C, A-C... If the three single phases are the same amperage... One must keep the load balanced to protect the generator and bearings. This may include adding additional load to a phase for balance. Reactive load is critical, whether it is Xc, Xl, or straight resistive. Be careful... Good Luck...

Thanks for the useful advice:)
