I understand that you cannot run the service thru one bldg into another but I assume the code is not talking about after the service leaves the meter base or outside disconnect on a duplex apartment. I just did new service on a duplex apt . The outside disc s are together on one end and I ran the feeders to the panels up into the attic crawl space and went over the first apt to the second. Was that against code ? It passed inspection but later I started wondering if that was why the original feeders went thru the crawl space under the apts. and not in the attic.
 
inspectors ?

inspectors ?

Are there any inspectors out there who will comment if they will pass inspection on a duplex apartment if the feeder to one apartment panel passes thru the attic of the other apartment.

It will pass in this area. In fact, it's about the only way it is acceptable.
The building inspectors will have you fire caulk around the cable passing thru the demising wall.

Ther duplex is old and there is no fire wall in the attic . Wow I would hate to chaulk that one at the price off fire chaulk , Ha Ha . Would it have been more acceptable to run the feeders under the building ? Thats how the old service was, but if you saw it you would see why I didnt want to go under !
Also is it better to run the feeder in pvc down the outside wall to the other apartment before entering the attic in a case where there is a fire wall in attic?
 
AHJ question for sure. Unsure how your Building Codes handle duplexs now and more questionable then. If may be permissible as built.

well it passed inspection but I hate to start thinking I did the right thing if I didnt. My common sence tells me it is not good for a live conductor to be in the crawl space of an apartment that supplies another apartment. But then again a building is allowed 6 disconnects and a duplex is a building and in this case no fire wall in the attic
 
It's doone every day in the jurisdiction I work for. There are condos's that on the outside look like a row of 4 town houses but in relality they are 8 stacked condo units.
The main service comes into a meterstack on each end of the building structure and the feeders go through the units to get to the respective condo's panels. There is no other way get the cbles to them.
Think about it this way, Is it any different then a warehouse type building?
Main electric room with the service disconnects grouped and the feeders going through each warehous bay to the respective tennants panels?

As you know these conductors are not service conductors but rather are feeders so the rules are different. I agree with the others that the feeders are allowed to go thru the other bldg.

Take a look at 225.37. This could be what you're looking for. Tony

This is very helpful and also shows that it is a compliant install.

225.37 Identification.
Where a building or structure has any combination of feeders, branch circuits, or services passing through it or supplying it, a permanent plaque or directory shall be installed at each feeder and branch-circuit disconnect location denoting all other services, feeders, or branch circuits supplying that building or structure or passing through that building or structure and the area served by each.
Exception No. 1: A plaque or directory shall not be required for large-capacity multibuilding industrial installations under single management, where it is ensured that disconnection can be accomplished by establishing and maintaining safe switching procedures.
Exception No. 2: This identification shall not be required for branch circuits installed from a dwelling unit to a second building or structure.

I only had to use mailbox letters to identify each apartment on the disconnects. On the condo's you mentioned do the feeders have to be marked any way in the attic crawl space ?
