IRC default code

[GerryB]

In CT the IRC is the default code for one and two family houses. Is that nationwide? Also the IRC does not include Art 406.4 requiring Arc Fault protection for replacement devices. Therefore it cannot be enforced by an AHJ. Thoughts and comments.

I am not positive, but my guess is most of the country uses the NEC instead of the IRC for electrical. We do not use the IRC for anything here.

Thanks. 48 more states to go. I had heard years ago you could use the IRC here but you were supposed to declare it on your permit. Never gave it much thought but if you could swap out devices in a house tamper resistant but not arc fault you save quite a bit on money (and headache ).

You do realize that the CT adoption of the IRC has arc fault requirements though in 3902.16, right?

Right, thanks for that. So that is new construction, but I see 3902.17 covers modifications and extensions. The hiccup is NEC 406 about replacement devices. I suppose a replacement could be considered a modification.

In VA residential construction falls under VA IRC. Aside from a few state modifications the VA IRC follows the NEC.

Thanks for the reply. So by VA IRC you mean the 2015 IRC, correct? That book does not have NEC art 406.4(D)(4) about replacement receptacles needing to have arc fault protection. Thus one could argue you don't have to arc fault protect replacement devices in a one or two family dwelling.
