i have a customer that has a 3 family home with a newer existing service, 3 meters, three panels. they need a landlord/ common area panel. i want to keep the existing service and add a new socket. the meter stack is able to tap into and installing the new socket is possible. my questions is, are there any codes i should be aware of to do this. i couldn't find anything against what i want to do. not adding any loads just moving all common area stuff to new panel. thanks.
