Which code to use here confusing

[Apurva Dave]

I have cluster of existing apartment buildings building #1,2,3....8 all joined by wall between each building.

They are doing utility upgrade so now their is one outside utility feeding new outside switchboard. The new outside switchboard has 2 new feeder breakers which have 2 new outside feeder feeding the cluster building #1 and #8.

Now one must determine if building #1 and #8 are considered separate buildings or cluster is considered one whole building. NEC 2014 section 225 says building can be fed by one feeder and there are no exceptions here. If building #1 and #8 are considered separate buildings then two outside feeder going to each building #1 and #8 ok but if not then you have one building with 2 outside feeder and need to correct to one feeder.

Cluster is existing and built by 1906 BOCA codes. However feeders going to cluster are new. Currently we are in IBC 2018.

Question: in order to determine if cluster is considered is whole building or has separate building so that amount of new feeder can be properly install per NEC 2014 Section 225 one needs to look at 1906 BOCA or IBC 2018?

Still trying to figure out

1. Does he just want all the new electrical to meet current code, as if the entire building was built the same today.

2. Does he want a change order.

3. Did he bid the job one way and find out missed by a million dollars.

4. Just cover the back side code wise

5. Or other

Was there a BOCA code in 1906? Do you mean 1996?

This question looks familiar, it might have been posted under electrical a few weeks ago.

It was the party wall question

Party wall

Is party wall a firewall or not a firewall?
