Welcome to another issue of JADE Learning's email newsletter. In this issue we have news from the North Carolina Board of Examiners of Electrical Contractors, a side-by-side comparison of several key sections from the 2005 and 2008 NEC, important changes in the 2008 NEC, and some brain teasers and optical illusions.
Thanks to everyone who completed our Homestudy or earned extra credits online to beat the June 30 deadline requirement for 4 hours of instructor-led classes. Online classes and written correspondence courses are still permitted, but half of the continuing education hours each year must be from a classroom course.
JADE Learning will be scheduling instructor-led classes throughout the fall in Raleigh and other locations across North Carolina. I look forward to seeing some old friends again and meeting new ones.
Thanks again for selecting JADE Learning as your continuing education provider. Please don't hesitate to contact us at newsletter@jadelearning.com if you have an experience, story, or installation tip you would like to share with us and the North Carolina community of electrical professionals.
David Burtt, JADE Learning.
