Watt Doc,
This is not an answer to your question, but I have to get on my soap box. There is a big difference between some one who installs electrical power and someone who repairs machinery. 7 years ago I hired a damn good journeyman electrician. He can bend conduit second to none. However since that is what he had been trained on his trouble shooting skills were, well let's just say lacking. Within a year he was what I would call a maintenance man, not only an electrician. One thing that I taught him was hydraulics. He had never had to work on any hydraulic systems before so he did not know it. I told him that it is logical just like electricity. The pressure is just like voltage and the oil flow is just like amps. Also if a machine is down you do not start in the middle of the control panel. Check for voltage at the disconnect, if there is voltage then move on to the next part of the panel.
Sorry if I have run on, I just wanted to put in my say.
Ultimate electrician, hard to say. Like you have pointed out there are two sets of standards, residential and commercial. I would say the ultimate electrician is one who knows a little bit of everything. And if he doesn't know is not afraid to ask. Also one who knows where to look it up in the NEC. Like Einstein said, I don't know what my phone number is but I know where to look it up.
He also has to take pride in his work. Very important.
I will know step down from my soap box and get back to work.
