NEC 230.70a1

[s.d. cronk]

Looking for some opinions please to help resolve a potential conflict.

There is a masonry block building with synthetic stucco being installed for the finish. The engineer would like to install a 2" conduit, extending from the transformer to the service disconnect, directly to the exterior masonry block. Then conceal the conduit behind the typical Styrofoam and stucco icing.

Would this be considered outside or inside the building for compliance with NEC 230.70a1 for the location of the disconnect?

Good Luck !!!!! this is one of those interpretation codes what I may think be readily accessible may be a totally different location for you. I don't think that the issue of the 2" conduit being prettied up is an issue Just the location of the equipment would be in question here. Just a point of advice when dealing with Articles and questions like these unless you want to redo the work if the inspector was to have a problem with it, or have to go into the ring to fight his ruling its always smart to get a hold of your inspector or ask him what he would consider would be "Readily" accessible.

In our area, depending on where the meter is located, that can be a utility installed cable--& under there jurisdiction..... In that event, they will not allow it to be concealed by the stucco (or anything else)..afraid someone will "tap" into it

I would say that they're considered inside of the building if covered by the building's finish. 230.6 lists four cases where the conductors are considered outside the building. Covered in stucco isn't one of them.

The NEC would probably allow it because the walls of the building are concrete block 230.6(2) might be applicable. Another arguement could be, if they are outside of the building without the finish then adding decorative (non-structural) material would not change their location.

However, the local utility would probably not be happy, although it is no different than the way a conduit riser is partially hidden by the roof eaves or is even goes through parts of the attic.
