In this episode, Russ finds an unusual overhead service drop. The service conductors are routed in PVC conduit, which was attached to the exterior siding of the building. Unfortunately, the installer must have used the wrong type of PVC and clips. As you can see they’ve become brittle and broken free. As required by Sec. 300.6(C)(1) of the 2017 NEC, this equipment must be sunlight resistant.
