OK I don't have a problem buying the books just didn't know if it would be necessary to have all them. I have been out of this line of work for about 8 years now. My dad had a Electric business and has passed and now I think I'm ready to get back in the business. I just have a lot to learn about everything. I already have one of his contractors that after I get my license and insurance he said he'd give me some home to wire! Getting my ducks in a row!!!
