Hint: Ugly UF cable installation.
There is a UF cable dangling out of the bottom of the Liquidtight Flexible Nonmetallic Conduit (LFNC) sleeve in a location where people walking by on the public sidewalk could inadvertently (or perhaps intentionally) step right on that UF cable. Section 340.12(10) prohibits installing UF cable where it is subject to physical damage. Section 225.21 requires supports for multiconductor cables installed on the exterior of buildings or other structures to be installed in accordance with Sec. 230.51. Section 230.51(A) requires cables to be supported within 12-inches of a connection to a raceway and at intervals not exceeding 30-inches.
This UF cable has no supports once it exits the LFNC sleeve. It’s just dangling in the breeze and strewn around underneath the deck. The LFNC sleeve is secured to the railing using cable ties. This is not a problem as Type 2s and 21S cable ties are listed for securing cables and flexible conduit and flexible tubing.
