A little embarrassing to even ask, but here goes. I have been "installing" electrical wiring in residential settings for a little over 18 years now. I have worked in commercial buildings and installed backup generators also. But the thought of taking a license test is all but absurd to me. I learned everything I know on the job, no codes, no mentoring, no classes, just repetitive installations. I have only had one job turned down in 18 years, but would like to do something with this work, rather than just installing and living from check to check. How in the world does someone even begin to take an unlimited test without having any experience whatsoever with 3 phase work, motors, etc? Reading the code book is often like trying to speak Russian to a Chinese because I don't have a clue what most of it is dealing with. But, I am pretty good hands on, just don't know how to gain the knowledge needed for the test. And, for 18 years, I have looked down on people who have taken the test and passed, but cannot install a receptacle. So, I've worked my way into a jam. Any thoughts on where to go from here? I have no intention of opening up a large company with many employees, just trying to earn a living for me and my wife.
