nfgo3: thanks, anytime.
I happen to be a licensed mechanical engineer. The studying and tests were grueling. In the end I am happy I did it. I spent 1 month trying to figure out the whole concept of “ohms”. As a residential electrician, most people will never come across such things. Not sure why it takes up a fair percentage of the test.
A few years after I received my “Master Electrician” license, I had some sort of mid-life crisis and changed profession.
There are many people however who have a “Journey-man” license. Which is a lower level license. That might be a good idea for someone not interested in training for as long.
