Anyone have any comments or suggestions as to how to approach this new code. Should this ground rod be added during pouring of the basement. What if there is no basement, how would you drive this rod that deep? Any comments for start of this new code are welcomed!
 
Re: New Residential Ground Rod Requirements

I'm not sure I follow your drift. Are you refering to the change in 250.50?
 
Re: New Residential Ground Rod Requirements

I am refering to the longer ground rod requirements along with the depth issue. Im not sure the Article number of where the code is found, I've just heard about it through the grape vine.

Are you talking about 2005's 250.50?

If the concrete encased electrode isn't there when I get to a house, I don't have to chip it out of the concrete. :)

There's a change bar by 250.54, but I fail to see a dynamic panic-worthy change. Then again, I'm not always sure that 250 is actually english. :)

En vino veritas.

Yep, thats the one. Is this something that will be enforced heavy. When will it be set in stone? (No Pun intended)

George, I am not so sure about that one. It will be up to the AHJ and how they want to enforce the new rule. In my opinion, if you get to a new house that is under construction and it has rebar, it has to be used. If you get to a remodel and it has rebar, it is existing and does not have to be used.

The AHJs in your area will have to decide how they will interpret the new requirement. :D

What are you talking about? :confused:
 
Re: New Residential Ground Rod Requirements

Here in my section of the good old USA (NJ) the AHJs make the builders bond the re-bar irrespective of whether it's a footing for a new house or an addition. As long as it has re-bar in it - it gets bonded. The good news is that you're not required to terminate it inside any breaker panel. You can bug it onto the water pipe ground or GEC wires before they enter the breaker panel.

Re: New Residential Ground Rod Requirements

Here in MA they added an FPN.

2002 Mass. Amendments.

250.52(A)(3). Add a fine print note as follows:

FPN: These electrodes, where available due to the footings not yet having been poured, are usually far lower in impedance than rod, pipe, or plate electrodes.

There choice of the words "footings not yet having been poured" leads me to believe they will not have us break concrete.

Of course that is 2002, I have not seen the 2005 Mass. amendments yet.

The Code permits the installation in that manner, you do not have to be from New Jersey, see 250.64(F). :D

I 100% agree. And I can 100% guarantee you that if I catch any flak from the AHJ on this one I will politely point out that he probably didn't think of it when he signed off the foundation portion of the permit. :D

They already practice this is Cheyenne, WY. I wish I would have known that once my water bond is installed I could have pulled that stinkin' UF'er anywhere... :D
 
Re: New Residential Ground Rod Requirements

I agree with charlie b. I think your going to find a lot of areas that adopt 2005 NEC will require the concrete encased electrode.

250.50 has been change to eliminate the words (if available).
At the Illinois IAEI winter meeting, it seemed to me that the IAEI is of the opinion that they should be installed. I for one plan on enforcing the use of the concrete encased electrode when we adopt a code change.
 
Re: New Residential Ground Rod Requirements

Bob that FPN reads exactly the same for 2005. So what is the bottom line is the concrete encased electrode required to be used or not. I see some of you are looking for ways to get out of using it. To me it is clear. New construction you must use it. Building renovation you are not required to use it. Obviously some coordination is necessary. But that is the nature of the business.
 
Re: New Residential Ground Rod Requirements

None of this addresses the original question of which I have no idea what the poster is talking about.
 
Re: New Residential Ground Rod Requirements

Scott, I have no idea on the face of this earth what I am talking about. Just overlook my post. I can't read. I caint evin speel. :D I was just told that we would have to start driving a 20+ ground rod and was told we would have to start grounding to the rebarb in the concrete. Im sure there is some truth to it but I need to further research this issue. This is why I posted the question, to gather a clearer picture. It seems that I am very far off.
 
Re: New Residential Ground Rod Requirements

Twenty foot ground rod. :eek:
