Hint: Droopy downlight
See the answer below.
Whoops! It looks like the plastic anchors that were used to secure this box have come loose. This luminaire is now in danger of falling onto pedestrians below, which could cause serious personal injuries if it were to hit someone in the head.
Section 314.23(A) requires surface-mounted boxes to be rigidly and securely fastened in place. Additional supports are required if the mounting surface does not provide adequate support. Perhaps using metal anchors would have been a better choice for support of a heavy luminaire.
Section 410.30(A) similarly requires luminaires to be securely supported. Section 410.36(A) does permit outlet boxes to support luminaires, but in any case, it must be done in a manner that both the box and the luminaire will be properly supported and secured, and neither the box or luminaire will fall. Fixing this situation should be relatively easy, but it needs to be done before it hurts someone.
