Article 230

[Tom G]

looking for maximum length service conductors can extend inside building and 230.43 [15] 6' is all I can find. must be more info in the code book than that. any suggestions

You won't find a distance in the NEC because there isn't one. Nearest is up to the AHJ to decide. Look at 230.70(A)(1).

Once the service conductors enter a building it isn't hard to see where the nearest point would end up being. Some states have amendments that allow 12', some 10' while others just look and see that if it is reasonable they will let it go. Check with the authority having jurisdiction or Wisconsin's amendments

yes thank you found it in Wisconsin admin code . 8' to nearest disconnect in group of disconnects

WA is generous with 15 ft of raceway, but restricts the wiring method, example no SE cable or EMT.

NC has a more complicated setup for service conductors

Service-entrance conductors shall be considered to be in compliance with the requirements of 230.70(A)(1) when routed from their point of entrance into a building or structure to the point of attachment to the service disconnect enclosure under all of the following criteria:

1. in the most direct route or at right angles;

2. horizontally not more than twice the nominal width of the service disconnect enclosure; and

3. vertically not more than twice the nominal height of the service disconnect enclosure or
five (5) feet, whichever is greater. Service entrance conductors in excess of these specified limits will not be allowed unless specifically authorized by special permission from the electrical inspector having jurisdiction to accommodate adverse site conditions which would not reasonably allow installation within this criteria.

I've always found this to be one of the dumbest code sections. There are areas of the NEC that micromanage the requirements and then they throw in this completely ambiguous definition of the word nearest. Why is 15' okay in Washington but not okay anywhere else?
