Does anyone know when Article 645 first came into being?? Ive run into to some of these rooms where they got the uninteruppted power sources etc. and their own ac unit to help keep the area cool, but it doesn't appear to wired correctly.
The hvac unit doesn't disconnect power then the epo button is pushed. Nor does the dampers closed for this area (NEC 645.4 2008). This are doesn't seem that old when it was wired.
For fire safety reasons, I would think this wouldve been required for a long time, but Im not certain. Any help would be appreciated.
