For those of you that do your own electrical work around the house or farm, I stumbled across this gentleman several years ago who over the last decade has built a really good training resource for both professional and do it yourselfer electricians.
You can keep up to speed of the latest NEC, buy training materials, or browse or participate in the forums with simple or complex questions.
Not being a licensed electrician but capable of performing all phases of electrical work under the supervision of a license holder has made this website a very valuable go to resource for me in calculating capacity, wire size, load, etc. for various projects I undertook that were a little more complicated than the usual 15/20A , 12/14ga wire scenarios. http://www.mikeholt.com/
