Q. On a flush mount over head services, rigid metallic conduit is installed in the structure wall from the top of the meter up through the roof line. Is it permissible to install rigid metallic conduit under the house in the crawl from the concrete wall to the meter location?

A. No. The service is required to be located nearest to the point of entrance into the building. Art. 230.6 does allow that the raceway, if encased in concrete, to be considered outside the building. (Tri-County Code Forum, May 9, 2002)

Q. When a fallen tree broke a meter base and incoming conductors, we contracted to replace those elements. The distance between the meter and the service panel was greater than code allowed for unfused conductors, so we installed a meter main and SER-type conductors to the existing split buss panel. As a cost-saving measure, we simply removed the bonding screw, installed a ground buss, and separated the grounds and the neutrals. Would this aspect of the installation be correct under NEC?

A. Yes. See Article 408.16, Exception 2002 NEC. (January 23, 2003 Tri-County Code Forum; approved by state electrical code chief for statewide application)
