Was wondering if anyone could direct me to the code article that pertains to the termination of the grounding electrode conductor in a multiple occupancy dwelling. The situation I have is a two level house with split occupancy service (service upstairs and one downstairs). There is no main disco that disconnects power to the entire house. From the meters outside there is one conduit to the inside of the basement straight into the panel for the downstairs occupancy, then a connecting conduit from that panel to the other panel for the upstairs. So when running the grounding electrode conductor, does it matter which panel the GEC terminates in?
