Question

[codequestion]

I have existing switchboard at backo of the building. The utility is feeding the switchboard. The switchboard has existing service system ground.

Their is a feeder from freder circuit brraker going to one of the tennanet space inside the building to Panel A.

Does Panel A is required to be grounded with electrodes per nec 2014 article 250 since switchboard is outside the building?

I hesitate to give an answer as I have found most of your "questions" are more of an AHJ opinion question than a Code question (likely by design)
The answer, IMO, lies in whether the switchboard and the Panel A are considered to be ""different structures which would be a AHJ question and possibly decided on such detail as the distance involved and the switchboard being attached to the building structure.

Typing with cell phone creates typos. It should read:

Their is a feeder from feeder circuit breaker going to one of the tenant space inside the building to Panel A.

Is Panel A required to be grounded with electrodes per Nec 2014 article 250 since switchboard is located outside the building? See attached sketch of existing switchboard location and Panel A location.

No. Typing typos and not correcting them creates typos.

You mean going too fast without checking them? Checking which ones were typo going back on small screen and then retype or type slower takes alot of time.

So don't spend the time to type up a coherent readable post, and make everyone else, who are already spending their time to help you, have a harder time??? Nice.

And why is that a problem? Isn't communicating clearly important?

So you think cluttering a thread with numerous repeats helps others trying to answer you?

No but it clarifies what i meant. It would help if their is an edit button taptalk mobile that changes the old thread instead of putting another thread. Thats what happens when you type from desktop it lets you type over with edit button.

You should be able to edit with Tapatalk too. Just select the post and pull down the menu. Note that all posts get locked against editing after about 15 minutes, so correct quickly.

I'm going with this ^^^^^^^

OP---In many cases, a lowly pole is considered a structure and therefore a GE would be needed at the building feed by svc on pole.

You need to ck out the ART 100 def of structure (yes, there is def for that in the code) for future reference.
