Do you know of any codes that restrick you from running undergound branch circuits from inside the building then out of the building and then back in. This is a commerical healthcare facility (non-health care loads). I have a panel on one wing and have to feed branch circuits on another wing. If I stay in the building I will be looking at a 350' run. If I run undergound and go out of the building and then back in I am looking at a run of 160'. Will I be in complaince with the NEC
