2002 NEC Section 230.6 Conductors Considered Outside the Building.

This is NOT a Code VIOLATION! This image only shows how the rule was enforced by an Electrical Inspector in the Midwest.

I heard a story one time that the ingenious installer just built a box and filled it with concrete mix ie. no water.
The bag(s) said "concrete".

This picture was relocated from the Violations area, and is still there and closed.

This location here is a better place for this image to be posted so that it can be discussed by those who understand the specific rule in 230.6 and how it is supposed to be applied. [Linked Image]

Joe,where would you as an inspector draw the line? Or could this be extended indefinitely?

While doing a remodel of a condo building we had to move the service from the cellar to the first floor lobby. We went about 30' into the building this way. We ran 2- 2" RNCs and the carpenters formed and poured them in.

I personally would have allowed the service raceway here, containing the service entrance conductors to be installed without the concrete encasement.

There are millions of these installations around the USA. During my own career while inspecting service raceways in the Northeast, I have seen many that had to pass over the oil tank to reach the service equipment because of the entry into a basement.

I believe the LA City Code includes some rule that allows the raceway with service entrance conductors to be run into a building for more than 25 feet.

I don't have that Code, so I cannot be sure.

If someone from the Los Angeles area can take a look, I would appreciate that help.

Would this particular installation have been used to obtain the proper clearance from the corner w/o using a disco outside?

I would say so, and the duct would have been a question as it relates to working spaces above, etc., rules

Pardon my ignorance here, but would it be a requirment for that lump of concrete to be tied to the wall, or can we just hang that much weight off of the box?

Since the maximum dimension is not specificed in the code, only the inspectors approval or disapproval makes it code compliant or not.

I don't think concrete should make us believe that the conductors are outside of the house. A drywall wrapping would appear equivalent.

A better location appears to be on the other wall, but I not would require that it be moved or that the conduit be placed in concrete.
