I have to say I'm not too keen on the fact that you're so comfortable stepping out of the bounds of what you should be doing. That may be carrying over to the guys in the supply house too. In most areas I know of a license (and Insurance) is required to do Electrical work for pay. I think I'd count myself lucky that no one has turned me in or filed complaints/charges yet.
As far as I know I'm perfectly legal here. My boss has insurance that covers this type of work. He carries a policy that covers his construction, plumbing, HVAC, and electrical work. I have worked under licenced electricans that pull the permit and then have me do the work, they get paied for that by the way. See,. if I think its too much I will call the electrician, he has told me that if its small just to do it and if he is busy, but if he's slow he askes for it. He's too big to fit in my tool bag though... This is too unreasonable?
