Hint: Worrisome waterway wiring
I spotted this mess while walking along a boardwalk over a pond and marsh area. The liquidtight flexible metal conduit (LFMC) has completely separated from the connector, leaving the conductors exposed. The general rule in Sec. 350.30(A) requires LFMC to be securely fastened in place using an approved means within 12 in. of the box or conduit termination. This LFMC is unsupported. Section 350.30(A), Exception No. 2, does permit 3 ft lengths of LFMC to be unsupported in sizes ½ in. through 1¼ in. where flexibility is needed after installation with the LFMC fittings being permitted as the means of securement and support. Perhaps a clip or two should have been used for this installation, since it appears as though the LFMC connectors were not able to perform the securement needed. The exposed wires are now much more likely to get damaged and possibly create a shock hazard.
