Addition to existing house

That is not out of the NEC and does not apply to me and many others. NEC is only code here and the number of amendments can be counted on one hand (even if it is missing four of its fingers).

But something like that may apply to others. If it does not apply to you ignore it, many others have.

This is a NEC forum. Questions and answers here should be NEC based.

I don't like seeing so many responses to questions that are are not based on NEC, reminders that there may be local codes or amendments is OK but this forum is accessable world wide and is not restricted to any single jurisdiction.

Smart where does it say where present when the service was installed.

If what you are implying is true when could you ever apply 250.54?

So you are saying that other building codes that apply specifically to electrical installations should not be cited here when answering an electrical question?

The building code has specific language about 'through' penetrations in fire assemblies that apply to electrical boxes; both the mechanical and plumbing codes have specific language as well.

Many electricians post questions here to get an accurate response - as such all codes that affect an electrical installation are applicable.

Yes, there is a world wide audience to this forum, that is why it is important to accurately cite which code is being used to answer a question or support an argument. As such, these 'other' codes may or may not apply to all of our audience, but by citing the source our audience can make that determination for themselves.

Well I am not sure but how does 250.54 jive with 250.121?

250.121 Use of Equipment Grounding Conductors. An equipment grounding conductor shall not be used as a grounding electrode conductor.

Lets stick with the codes that are in use.



But that looks like it will have to worked out.

While the NEC is 'National', building codes are not, so if we all start posting random building codes I do not see how that will be helpful.

Bob if the cee is installed why would 250.54 come into play. That is for auxiliary grounding electrodes. I didn't think a CEE was considered an auxiliary electrode.

NO.

Let me try a simple example.

I add a new bedroom circuit. AFCIs?

I add a bathroom. GFCI?

I add an electrode. Do I have to connect it?

OP

They added two bedrooms and a bathroom. Where going to install a sub panel for it. The footing has a ufer there for grounding. I was going to run a feeder cable with a ground, from the main to the sub panel. Now what do I do with the footing ufer? Do I run a GEC from the main to it? I know your suppose to utilize it if it's there. Thank you for your help.

OP added an electrode. He probably does not have to connect it but he is asking how to connect it so apparently he intends to do so. Once he decides to connect it he should do it correctly. My opinion is if there was no CEE connected to the service and he decides to add one it should connect to the service and not a sub panel. If he would have added an underground metallic water pipe the same would apply to that.

If you are getting an answer to a question from someone that knows what the other codes in the area are then let them say what it is.

If you are answering a question for someone in a different area and have no clue what other codes may apply to them the most you can do is remind them that other codes may need consideration, and they need to find out what does apply.

I don't like how many questions are answered with a 'this is how it is' tune to them when it is really only that way to the responder. A better response would be 'I don't know about local codes where you are at, but in Anycity, USA we are required to...' instead of throwing us a local code rule and act as if it applies to the entire world.

If you want an answer to a building code issue go to a builders forum. I bet there is a lot more confusion on them type of sites. You will get a lot of different answers to a question on this site about other codes, but NEC questions will have more fairly one sided answers. There are still times where something is not real clear, some of us look forward to these problems no matter how simple they may seem, they can make you learn things differently that you thought you already knew. NEC is pretty well accepted as the standard in a lot of places so we are lucky to have a more uniform code than many others.
