A service lateral stubs up into a junction box inside a carport. Inside this junction box are spliced service entrance conductors that run in several pipes down into the cement floor where the cars are parked and out and under the lawn to several apartment units' service disconnecting means. One of these pipe runs is faulty and needs replacement.
The electrical contractor wants to avoid breaking up concrete in this carport in order to run the replacement. He asks if it is ok to run the pipe replacement raceway up out of the junction box along the wall over a doorway and out of the carport (a distance of 12 feet) and down the wall into the ground to the unit's service panel.
Sec. 230.3, NEC 2011 requires that service conductors supplying a building shall not pass through the interior of another building or other structure. This replacement method appears to violate code. Do you see any problems with passing through the interior of the carport as the contractor would like to do?
Thanks
