What is the requirement for conductors used for direct burial applications?

For conductors used in direct burial applications, it is essential that they are specifically identified for such use. This means that the conductors must meet specific standards and regulations that ensure their suitability for being buried underground without additional protective measures. These standards address various factors, including moisture resistance, environmental conditions, and mechanical protection, which are crucial for maintaining the integrity and safety of the electrical system over time.

Conductors that are not specifically identified for direct burial may not withstand the environmental conditions they encounter, leading to potential failures, safety hazards, or code violations. Therefore, using conductors that are designated for direct burial is critical to ensure compliance with electrical codes and to promote long-term reliability and safety in electrical installations.
