I got a call from one of our GCs today asking me about bonding to slab rebar. He is getting ready to pour his next house and the inspector tells him the rebar needs GEC attatched to it. I told him of the requirement but it is the first such enforcement I have seen in countless houses. He said it is the first he has been gigged and he has been doing houses for 25+. So I hopped in the truck and drove over there and have not heard anyting so I am assuming I got everything right. Thought I would share my rookie adventures 13 years into it. :grin:

I hope you aren't saying you completed a job without having any idea on how to do it? See 250.52 (A)(3):cool:

Yes, I double checked my understanding of the code and even called an inspector to friend for a second opinion. As I was driving to the job I remembered forum discussions and thought I should have just had the masons stub out a piece to tie to later.

IC. It's not an NEC requirement. Yet, some local rules may require you to use the re-enforcement bar---if it's accessible (New Construction, before they pour).

I don't know if that is accepted in all areas, how would an Inspector know how long the

stub is? Also, IMO, I don't see that the NEC has words to support that type of install.

It will fail here. Rebar cannot be in contact with the earth. It will rust off and you will have no ground. Here in Florida, it is turned up into the interior framing or into the open cell of the concrete bolck construction. Accsess hole is required for connection. Framing inspector looks for the rod turned up before concrete pour.

Essentially, what I told the GC, is that it is a requirement, but rarely enforced because by the time the EC gets there, it is not accessible. The "sometimes interpretation" and probably the more correct, is that the EC needs to be present at the time the reinforcement steel is accessible. I just thought it was kinda funny that after 13+ years of doing almost exclusively residential work, this is the first time it been an issue.

Hence, my little smiley face. If I remember, there was about a 6000 post thread on the validity of stubbing out the rebar.

The NEC does not allow you to use that as an excuse. If the rebar is present, and by your own words it is, you have to use it. This applies to new construction only.

Also you mentioned rebar in the slab. Is there no foundation?

Most importantly, if the inspector is telling him it's required, and the inspector is correct, I would think you should make sure it gets done.

YES it is a an NEC requirement. Code also says if present not if accessible depending on which cycle you are in.

Actually in NC it is "if availlable", NC ammended the 08 (and 05) to keep the wording of the 02.

I know NC takes a don't worry about it attitude but I have been working diligently with my builders to ensure I get my copper in the footer. Sometimes stubbing up doesn't get it so I install 20' of #4 in the footer and tie to the rebar. I realize the 20' is not necessary but I like wasting money.

Sure it is,250.52(A)(3). That's what we require here.
