I think it depends on the builder. Im talking production builders, build entire communities, literally here at the coast we are talking thousands. The contractors follow the builders plans to the exact specifications. I have some experience with this in our new home and past production home.Yeah, it is the electricians as they will almost always follow the NEC, then maybe adapt to the local rules. Electricians rarely work in a single city so they need to follow a higher standard. Use the city of Cincinnati OH as an example and they have an inspection department. The next day they could be working in Northern Kentucky (a whole other state) with different inspectors, then in West Chester or Batavia, again with different inspectors (the names of the cities, etc aren't relevant).
Just using the topic of this thread as an example. The NEC says "no outlets on the sides of kitchen islands" so 9 out ot 10 electricians won't install them even though city "X" allows them. Electricians don't contact the inspector to ask "what revision of NEC do you require?"
For example We were missing some low voltage outlets for the TV and one 110 line.
First thing when a warranty claim is filed is the contractor is off the hook if it wasnt in the plans from the builder. The builder then picks up the cost.
I am saying is here in SC/NC areas after all this is a big country so I am not doubting your post Ive never seen a disconnect on the outside in NC and never been in a new home in NC (yet, Ill keep the thread updated) with no outlets on the side of the center island.
About every month my wife and I walk through new constructions.
I do have a family member who just purchased on the SC side (brand new) and I know he has the disconnect now I will ahve to see if he has center island outlets on the side. I never checked and it's a huge center island. I see the disconnects on all the new homes in SC.
