When I worked for my boss back in 1975-1984 he was liscensed and I was not. Did I do side work? Yes, but it was for my parents, my brother and my grandfather, but that was it. I didn't do work for other people because I didn't have a lic., nor did I have insurence in case of a problem. I know that a lot of people have "Friends" who dabble in electrical work and they are not lic., but IF something did happen, will an insurence company pay out if they find out that the person who did the work was did not have a lic. I am not too sure. I am a AHJ now and people still ask me to do side work, BUT I don't have insurence in case something goes wrong. I will not work for anyone without the insurence to back me up.
