Look at the weather head on the tip of the mast. It should be intact and in one piece. Look for conductors to potentially be rubbing exposd metal surfaces here. If they are rubbing or have been rubbing (even if the plastic is not rubbed through) this situation needs to be corrected as this could cause a service outage as well as be a safety issue. As you can see in the picture of the weather head, the plastic sheath has rubbed off and is exposing the aluminum conductor. Even though the weather head is isolated from the metal structure with a rubber insulator, water could create an electrical path between metallic surfaces causing a electrical short. This condition should be addressed by a licensed electrician.
Key inspections and action items:
- Visually inspect the service drop entrance into the weather head for wear, distortion or damage.
- Contact an electrician for correction.
