The description of the purpose of a weatherhead.

Explanation of Solution

Weatherhead is the fitting located on the service drop end of the service entrance raceway or service entrance cable. The other name of weatherhead is a service head.

Weatherhead is designed for the reduction of the moisture amount which can access the raceway or cable.

The aim of the weatherhead is to prevent water from entering the end of a service entrance cable. Every service entrance conductor has to exit the weatherhead from a separate hole.

Service raceways at the connection point should be fitted with a weatherhead to overhead service conductors. Service entrance cables should be fitted with a weatherhead specified for use in a place that's wet. Through independently bushed openings in the weatherhead, service entrance conductors should be carried out.
