What's Wrong Here?

David Lewis, a service technician and assistant manager for Haymaker Electric, found this keyless lampholder in the electrical equipment room of an 18-story office building in Birmingham, Ala. The lampholder isn’t secured to the outlet box because the installer didn’t use the supporting screws. As a result, it’s hanging from the switch leg and the grounded circuit conductor. The wire connectors show where there were other spliced conductors that have been cut away. However, the use of a long screw at the termination is the real issue here because it’s being misused. The person responsible for this installation clearly isn’t qualified as defined by Article 100.
