Which type corresponds to Article 353?

Article 353 pertains specifically to HDPE, which stands for High-Density Polyethylene. This type is often used in the electrical industry for non-metallic conduits and is recognized for its durability, elasticity, and resistance to corrosion. HDPE conduits are suitable for underground installations and can withstand environmental stress, making them ideal for various electrical applications that require reliable insulation and protection.

The distinction of HDPE under Article 353 is relevant for professionals in the field because it indicates compliance with specific standards for installation methods and material properties. These characteristics offer advantages such as ease of installation, flexibility, and long service life, which are critical considerations in electrical system design and implementation.

Knowledge of Article 353 and the properties of HDPE conduit helps electricians ensure they select the appropriate materials for safety and performance in their electrical systems.
