Re: Residential Panel 15 foot rule
This is not covered in the NEC except as Bennie mentions. Its a local regulation. In Washington State it is 15ft, and the type of raceway is restricted.

Shock Me,
Look at 230.70(A)(1) for the general rule on this. Basically it just says it must be a Readily Accessible Location ... "nearest the point of entrance of the service conductors". This means different things to different people. On Long Island it could be called the '5 foot rule'.

Re: Residential Panel 15 foot rule
Where I live this is a gray area the dicision is left up to the inspector,the unwritten rule is 3 ft on residential, I have seen more unfused wire permitted where its in grs or where the construction method is masonary or steel in commercial work. My brother bought a condo in buefort county sc they accepted 45 ft in stick frame construction, pretty scary ever seen a screw driven thru 2 phases ,or a phase and neutral that are not fused .When we asked why they said that aint the way we do it in buefort county.

Re: Residential Panel 15 foot rule
As Tom mentioned, Washington State requires a disconnect within 15 feet of entering a building. However, if you encase your service conductors in concrete, the 15 foot limit does not start until the conduit pops up out of the concrete. So you can go 100 feet or more into a building by putting the conduit in the slab, pop up into the electric room, and then go 15 more feet to the first disconnect. Is that similar to what you are describing?

State of Wisconsin is 8' per COMM 16.25 (4)(a)dated 1999. (current edition)
exception: Can exceed if Service Entrance busway is used.
The 8' starts at the point where the raceway or conductors pass through the outer surface of the building.
