Two business ,side by side with a firewall separation. If there are main disconects located outside, Can a feeder pass through one structure to supply the other. sec #230.6 is about service conductors. what applies to feeder going through one building to serve another ?
There is nothing to prevent such an installation in the NEC.
The only rules I saw here in Mass is they wanted it sleeved and fire caulking applied.
Don't know of the rules where I am, but I know of one buinsess establishment where such a situation apparently is so.
I'm thinking of 230.3 and that is also regarding service conductors. I guess that's because Article 230 is titled "Services".
If there's only one service I don't know of an issue.
there are 2 services, one for each building. feeder is passing through building # 1 to supply building # 2
