I am reviewing a design and have a question regarding how the service is set up with disconnects. NFPA 70-2017 is the governing code in this jurisdiction.
This is an existing building that is currently occupied by one tenant. There are currently two 200A meters, fed by one 400A overhead service. The service is spliced into two weatherheads, one for each meter. Each meter feeds a distribution panel with main breaker. The two meters are grouped outside. The two panels are separated by approximately 70 feet indoors. The new project includes demising the building into two tenant spaces and adding a landlord room. The intent is to upgrade the service to 800A and provide a separately metered feed to each space.
The original design included bringing the new 800A service to the building, upsize one of the existing 200A meters to 400A, refeed the other 200A meter, and feed the new 100A landlord service. The part I am struggling with is that there are no disconnects shown other than the main breakers on the distribution panels.
Would it be code compliant to install in this manner? One service, tapped to each meter, with disconnects within each space as described? Or do disconnects need to be installed at the service taps? I'm thinking this is compliant based on 230.40 Exception 1.
