This isn't one of our jobs but when a friend asked me why this was required, I had never heard of it.
It is a new 200a overhead service. He ran the 2" rigid down the RH side of the house then penetrated the exterior wall into a storage room. Once it enters the storage room, there is an LB and the conduit goes about 18" and penetrates another outside wall where the disconnect is located. The conduit is (will be) in a soffit once the job is complete. My friend said that because the 2" rigid goes into the storage room which is part of the dwelling, that the conduit must be concealed in 2" of concrete. Now I'm not exactly sure how he would do that since the conduit is 7' in the air, but that's another story. Has anyone else heard this? I was thinking about it and I can't actually think of a time we had the service come into a dwelling area like that, but I don't see what good the concrete will do. A code reference would be appreciated either for or against.
Thanks
