If you can edit your title ( and move it to electical forum) you'd probably get an answer from someone who actually knows, but I'll give it my best guess if that's any help:
There is probably nothing in the NEC that requires this, but you will need to pull a permit for sure, and the local code may require it. Your permit office would be the place to start.
Like I said, just a guess, so take it for what it's worth. If you can edit your title to be more specif to your question, that would attract members who probably forgot more about the NEC than I'll ever know
Those who can, do...
Those who can't criticize on the internet
