Changes

Is there a thread on the pertinent changes of the 2005 and 2008 codes? Just looking for a concise list for a short class that will be given here. Thanks!

Not a single thread that I know of... they're scattered all over like birdshot here.

I am sure you will find plenty, but also plenty you will have to wade through to find the info you are looking for. Another thing to remember is that not all jurisdictions adopt the same changes. Many here have suggested that members post their location to help with such questions. At the begining of the year I got one of those CEU course boks in the mail that had very nice details on 2008 changes, but I do not know how to go about getting one. You can try here to see if there is anything worthwhile. Are you trying to study ahead?

The code change book that Mike offers (see main page) is well worth the money.

Thanks for all of the good reference sites. I have one other request though. Tennessee is just about to go to the 08 from the 02, so I also need some references to changes in the 02 to 05 if you have any.

try google and you will find stuff like this
