As an EE, I say ask one specific branch of the Electrical Engineering profession. see [1], here there are 3 specific sub disciplines you can test in, and all are considered "EE" computer electronics power you want to talk to an expert in the power arena, but from what I remember when studying for the exam, the content was mostly things way above residential (which is what this discussion has been about) and more of power gen and conversion.
