Brian is a very valuable resource here in SW Florida. He is getting his presentations certified by the state for CEU credit and usually they are free for IAEI meeting attendees. He is also a driving force in the IAEI. Quite a guy. All the thanks go to him.
I don't mean to be demeaning, but where are the illustrations. I have been preparing my CEU 2011 Change course for approvals for the last two months. The state of Washington requires 200 questions and I have been building 200 illustrations, one for each question. It takes me up to 3 hours to build an illustration and many times I have to go looking for something to take a picture of. I just wished they had those digital cameras around when I did 4,000 inspections for the State of Alaska from 1988 to 1996. I have put 140 of my illustrations online in slide jpg format at http://www.electrician2.com/2011nec1/2011_nec_ifchanges/2011_nec_changes.html I still have 60 to go.
Gerald, you are just given the references so you can look them up in your handbook. This is not intended as a way to sell CEUs. This is a free guide, prepared by a guy who has a full time job running a building department. The words "Gift" "Horse" Mouth" occur to me.
