NEC 700.9 (B) states that "wiring from an emergency source...to emergency loads shall be kept entirely independent of all other wiring and equipment."
Where does the emergency system wiring begin?
I have a separate emergency service which feeds an ATS also fed by a generator. Is the wiring that comes from the vault to the emergency main considered emergency system wiring, ie, do I need to keep it separate from the "normal" and "optional standby" power feeds coming from the vault?
The Contractor provided a separate pull box for the normal power, but ran the emergency with the optional standby in the same box.
