Just recieved a copy of the 2018 CEC the other day at work. I inquired if we code get a copy of the 2018 Code Explained to go with. Lot of really good information that sheds light on certain code rules. Anybody else typically buy both?

I had one some years back and I'll never get another.

In Ontario we use the OESC and the new version won't be out until 2019. Then I'll take a course from the ESA to learn the changes.
So, anything interesting that I have to look forward to?

I used to buy the NEC "handbook" essentially what you are talking about but I haven't had one for several cycles. I still refer to it on things that haven't changed tho.

Curious as to why?

I found that certain code rules were explained in far greater detail and some others included examples of calculations, etc.

I thought Section 10 was supposed to have a lot of changes. A first glance I didn't notice anything exceptional. I believe all changes have a triangle symbol next them? I will look again when I'm back at work (currently taking some vacation time).
