Hint: This cable needs some sunblock

I spotted this NEC violation while vacationing in Arizona. That’s a nonmetallic cable coming out of the wall and running up the side of the building.
Using NM cable outdoors in this wet location is a violation of Sec. 334.12(B)(4). In addition, NM cable isn’t sunlight resistant as required in Sec. 300.6(C)(1). Section 334.116(A) tells us that the outer covering is flame retardant and moisture resistant, but says nothing about it being sunlight resistant. The hot Arizona sun will eventually cause the jacket to become brittle and dried out, destroying it in the process.
The NM cable connector sticking out the side of the building is a violation of Sec. 110.3(B) since it is made for use in dry locations only. The support requirements of Sec. 334.30 state the NM cable must be secured within 12 in. of every cable entry into cabinets, boxes or fittings. This cable is stapled about 3 ft away from the connector. Spacing the staples too far apart can allow the cable to be more easily damaged due to drooping or sagging in the cable.
While there are many problems with this installation, at least the installer was thoughtful enough to install a “drip loop” on the NM where it enters the building.
