I am doing a project with a big cooler warehouse building and a big freezer warehouse builidng. They are connect to each other. I believe they are separated by fire rated wall. The owner owns the primary service including 12kv primary utility meter and switch, 2500KVA 12kv/480v transformer for the freezer building and 1000KVA 12kv/480v transformer for the cooler building. Primary utility meter and swtich, transformers are located outside the building. I am not sure how many service we got. For the whole site, it is one service from utility company. But for the building, it seems two service one from each transformer.
If the site as a unit and it has one service, how many service disconneting means are allowed to be installed on the whole building? How does the six disconnect rule apply to the building? Thanks.
