Just got done my 15 hr code update on the 2005 code. Maine requires it every code change and this class was done by a Maine inspector. Good class.
Trivia questions raised in class.

Does the NEC define a sub panel??

Is EMT conduit?

Last but not least
under 334.30 NM cable
"Sections of cable protected from physical damage by raceway shall not be required to be secured within raceway" [Linked Image]

I know other states require code updates, do you take a class?, do home study? over the net??
