Hint: Sloppy sign wiring.
There are three separate sections of Liquidtight Flexible Nonmetallic Conduit (LFNC) I want to examine here. The short piece run between the lowest box and the middle, blue-painted box has part of the box connector unscrewed leaving the raceway not fully secured to the top box as required by Sec. 300.11(A) (Sec. 300.13(A) in 2026). The next piece I want to focus on is the one connected to the right side of the blue box. If we follow this raceway, we will see it loops up and over the top box and is run into the bottom of the sign enclosure where it has come loose from the locknut originally used to secure the connector to the sign. Now the raceway is dangling by the wires! This is another violation of Sec. 300.11(A) as well as a violation of Sec. 300.18(A) which requires the raceway to be installed complete between these enclosures. The last problem is the LFMC run up the side of the sign. This long section of LFMC has no clips or supports as required Sec. 356.30.
