"Here is a photo at the front door of a Mexican restaurant in Houston," says Paul Diverter, a reader of EC&M. "The place is relatively new, maybe open now for six or seven years. The door is metal. It is relatively dry in this photo, but everything gets covered with water when it rains. I wonder how many more people are going to step on the metal tread plate before the insulation finally goes."

First, this flexible metal conduit (FMC) has no fittings to ensure its electrical continuity as an equipment grounding conductor. In addition, FMC is not permitted to be installed in wet locations or where subject to physical damage (348.12).

The insulation on these conductors could easily become exposed and lead to an electrical shock.
