On a recent quiz question on Mike's 2014 update code class, they state " on trade size 2 and larger...
Are they referring to size as in inches or what? I can't find a definition or informational note pertaining to that.
Thanks!
 
If you look at the tables in Chapter 9 of the NEC, you will see that "trade size 2" means a 2 inch conduit.

Since this is your first post, I would normally say "welcome to the forum." But I see that you have been enrolled for a while. So I will instead say, "welcome to active participation in the forum." :happyyes:
