Is it acceptable to have an 480V 3ph, 3w electrical service for an office building? I have only designed 3ph 4w systems so I am wondering if anyone has any knowlege of such a service or can direct me to a reference. I am assuming since it is before the service disconnect that it will be covered by the NESC rather than the NEC.
