Comments: what is your "interpretation of 230-6?

Would you approve a c.t. can inside a room with the disconnecting mean and the meter 8 feet inside on a wall adjoining the main body of the house!

I believe the conductors are to be outside the structure or encased in 2" of concrete or brick.

My supervisor believes the article 230-6 is superceded by 230-3, and 230-70 as the disconnect id immediately inside or close to the point of entry (his terms)

In the areas of NJ that I am familiar with:
18"; 12", "as close as possible"; 3'; and "none". ie: into the back of the panel or main disc at the point of entry.
It is a decision by the local AHJ; it's best to get that "decision" prior to the install if you are not familiar with the locale.
The other alternative is concrete/brick encasement of 2" on all sides.

Being "around for a while" fortunately I know most of the areas, until a "fill-in" inspector shows up.

Your interpertation is the same as I look at it.

When you say "c.t.' are you referring to current transformer? I do not do resi. Why would they put a ct cabinet in a house? Over 400a?

I agree with John, I have seen a lot of different distances on the inside of the house where the main service is located. The AHJ will have the final word on it. If I was inspecting the job, I would want it as close as possible, as safe as possible or encased in concrete. I have seen where a cable would drop from the ceiling down 4 feet, but it was all above 6 foot high so that you couldn't reach the service cable. I have also made guys install pipe in concrete when they ran a service inside the building because the pipe was subject to physical damage. It is a hard call to make. Get the AHJ out there before you do the job, and I think everyone will be happier.
