What is required for cables or raceways installed using directional boring equipment?

Cables or raceways that are installed using directional boring equipment must be approved to ensure they meet the necessary safety and performance standards required for underground installation. This approval is crucial because the installation technique involves creating a borehole beneath the surface, which can be sensitive to the type of materials used. Approved cables and raceways are designed to withstand the unique stresses and environmental conditions they encounter below ground, reducing the risk of future failures or hazards.

Additionally, using approved materials guarantees compliance with local codes and regulations, which is vital for both legal and safety considerations in construction and utility projects. This approval typically comes from relevant authorities or standardization organizations that set guidelines for quality and compatibility with systems being used. While standardization, flexibility, and cost can be important factors in material selection, the primary requirement in this context focuses on obtaining approval to ensure reliability and safety in the use of directional boring methods.
