NEC 2017 section 225.32:
The disconnecting means shall be installed either inside or outside of the building or structure served or where the conductors pass through the building or structure. The disconnecting means shall be readily accessible location nearest point of entrance of the conductors. For the purposes of this section requirements of 230.6 shall be utilized
NEC 2017 section 230.6:
Conductors shall be considered outside of a building or other structure under any of the following:
(1) where installed under not less than 2inch of concrete beneath of building
(2) where installed within a building or other structure in a raceway that is encased in concrete or brick not less than 2 inch thick
So in attached sketch side bu side building with firewall by building code make it separate buildings and have fdr#1 and fdr#2 go thru 2 inch concrete or brick firewall lets say then would they be outside feeder and would require disconnect per NEC 2017 section 225.37? Am I correct or incorrect?
