What is the appropriate installation guideline for the top end of an SE cable service?

The guideline that specifies that the top end of an SE cable service should have a gooseneck before the splice is essential for ensuring proper drainage and protection of the electrical service. The gooseneck configuration allows for any water that may run along the cable to drip off rather than potentially entering the splice area or the service panel. This is crucial because moisture can lead to electrical failures, corrosion, or even fire hazards, especially at connection points where the integrity of the electrical path is critical.

In residential electrical installations, a gooseneck helps in maintaining the integrity of the installation and promotes safety by reducing the risk of water intrusion. Proper installation practices in service entry cables are important for compliance with electrical codes and for ensuring the longevity and reliability of the electrical system.
