OK here is the outcome I spoke directly to Ron Chilton from NC DOI and I also produced pictures of the service. He stated that although there are no wall under a pier built home it is still considered in the building envelope, I said OK i'll install the meter on the adjacent side of column which actually would be the exterior of the dwelling went up the outside 4 ft and then in with the same SEU. He said that was fine and so did the inspectors after I told them if they insist on a disconnect on the exterior then they have to take it up with the DOI. I am happy I just had to pull out the SEU and meter and remount took about 1 hour. I guess that would actually be the building envelope just thought it had to have enclosed walls but its done. Thanks very much guys Rich.
