? Are their any NFPA code reference for extension cords use / violations
such as not being used for permanent placed commercial kitchen equipment?
or through ceiling grids
Commercial cooking equipment will usually have electrical requirements to have a "dedicated circuit." Try to investigate the actual equipment being used, and go from there. Installation manuals can usually be found online. That is how I do much of my NEC plan review. If there is a requirement for the item to have it's own circuit, and it is being powered from an extension cord, it is a violation of NEC 110.3(B):
"Listed or labeled equipment shall be installed and used in accordance with any instructions included in the listing or labeling."
The installation instructions are part of the listing.
The problem with enforcing this any other way (IMHO) is that when you get to court, they will simply "unplug" the extension cord and *poof* the violation has disappeared...
