I have a garage we wired with a sub panel, it is attached with a breezeway, (deck on bottom roof attached on both structures) about 8 foot wide.I deem this attached, I wired with four conductors separating neutral and grounds.
Inspector is asking for ground rods to be driven, at garage .what section in code verifies we don't.? This is a different inspector a neighboring county. I know 250.32. Deals with detached.

also having a peeing contest about sunlight resistant not being on cable, I got that one covered.

thanks

We the installers do not get to decide what is attached and what is not. That would be an inspectors call.

If the inspector feels it is a separate building or structure the code section requiring electrodes would be 250.32(A)
 
Ok suppose it is attached, by everyone's standards, what section tells us we don't need ground rods, thanks for quick reply
 
Its more a case of what section does not.
For the most part the NEC is permissive... if it does not say it's required then it is not.250.30 covers DETACHED. If its not detached , no 250.30 requirement.

I agree.

To put it another way, what section tells us that we don't need ground rods driven for a sub panel in a basement, or anywhere else in the house? The code doesn't tell us what we don't need to do, it just tells us what we are required to do, or are not allowed to do.

If the breezeway (unenclosed) is 100' long is the garage still attached? Where to draw the line?

That sounds like a stretch, where is size mentioned in the common definition of attached? Attached is not separate the word which is used in the NEC.
 
If the breezeway had walls, I would have no problem at all with attached.
Just the walkway, I would say detached.
So it all comes down to the roof....
One way of looking at it (not for NEC purposes) is that there is no risk of CO infiltration through a structural connection.
