International Residential Code

[electrify-U]

I just found out that Utah has adopted the 2012 International Residential Code for one and two family dwellings.
I had been using the NEC.
What are the differences?
Do I need to buy an International Residential Code?
Does someone have experience with this?
Thanks for your help.

Yes there are some differences, most of which will be found in the building code sections of the IRC.

Example placement of light s in stairways. The bottom landing principle dose not work well for basements. Or top landing for second story stairways. You will need a light at both the top landing and bottom landing controlled by the three-way. Or you will need a fixture placed over the stairway section which is the preferred method used by most builders.

Bonding of corrugated stainless steel gas lines

If you are not used to inner connecting smoke detectors this will be a change for you.

You should purchase the IRC so you can reference the code section being discussed.


There are some other differences but for the most part the 2012 IRC electrical provisions will be based on the 2011 NEC

I found a copy online. I could not find a reference in the document that takes you to the NEC. Doing a quick review it look easier to follow.

I would simply call the AHJ and confirm what he wants you to follow.

Interesting state to do it in; there would appear to be a similarity with another couple books. :jawdrop: Not gonna touch that one:angel:

The proliferation of this code and that code, and yet more codes leaves me with the feeling of - "it's all about the money".

Have I missed something?

I see no logical reason to have anything else than the NEC.

With so many putting in their two cents regarding electric it's becoming impossible to keep track!!!

If you had followed the history, the International Code Council tried to write it's own electrical code and was sued by the NFPA, because they also one the rights to the name International Electrical Code. The code council then gave in and decided that it was better not to reinvent the wheel. The residential code was supposed to make it simpler for those that only do residential and didn't need to be bothered with all the rest of the stuff in the I codes and the NEC. Remember that there are things in the building code that are not in the NEC that you as an electrician are usually responsible for (smoke/CO alarms, exterior emergency lighting, exit signs, path of egress lighting, securing of lights in suspended ceilings, just to name a few.)
