Hey guys,
I have a question while re-practicing the Cram for Exam questions.
How does a grounding bank provide current to a load? See the attached problem 26 from Cram for Exam Vol. 3.
I see their explanation that the grounding bank doesn't provide any power to the 1-phase load, but it still doesn't explain how the load gets 1/3 of its total current from the grounding bank...
Does anyone know an explanation to this?
Thanks for any input on this!
