Please accept this as a code violation for "What's Wrong Here?"
Flexible cords and cables are not permitted as a substitute for fixed wiring and should not be concealed behind walls.
This photo shows an outlet that was uncovered within an office building when some sheetrock was removed during a major renovation project of the facility.
Please note that the building was purchased by a local University, and the electrical installation may have been done by the original owners.
I believe that this installation could be considered for several violations, but I have
chosen NEC 400-8 (1) and (5).
