Significant Changes in the 2011 NEC

[bphgravity]

Hello Everyone,

Though it is likely more than year from now that the 2011 NEC will be adopted by the Florida Building Commission, I feel it is never too early to get prepared. It is my understanding the Commission is making every attempt to adopt the 2010 FBC along with the 2010 FFPC and 2011 NEC, all at the same time. This makes for an awful lot of code change to sort through. To give you a jump start on some of the more significant code changes that were made to the 2011 NEC, I have prepared a list of those changes I feel will have the greatest impact. (See Link to IAEI Website) As you should expect, the list is not all-inclusive.

Over the next several months, I will incorporate these changes into a power-point presentation. I will distribute that to anyone interested at that time.

I hope you all have a great week.

Take care and be safe,

Thanx!

I know the next code cycle is going to be interesting for me.

I am on 2005 and learning 2008.

I am moving soon to an area on 2008 and will probably adopt the 2011.

It is gonna be challenging, to say the least.

new codes

new codes

This may not be the right place to ask this, but where can I find out when my state Georgia and other states are adopting the new code?

Earl check out your states lisc. website, I know from what I saw on Maine's it even gives you when the code cycles will be adopted for the next few, think I saw ahead to 2014 at least here in Maine. anyhow that may be the place to start.
