Which type of conduit is often used in applications requiring non-conductive properties?

Non-metallic conduit is designed specifically for applications where non-conductive properties are essential. This type of conduit is made from materials such as PVC (Polyvinyl Chloride) or other plastics, which do not conduct electricity, making them ideal for environments where the prevention of electrical conduction is crucial. These conduits are commonly used in residential and commercial electrical installations, particularly in wet or corrosive conditions where metal conduits could pose a safety hazard.

In contrast, metallic conduit, including galvanized varieties, is conductive and can introduce electrical risks in certain situations. Rigid PVC conduit is a subtype of non-metallic conduit, but the broader category of non-metallic conduit encompasses various materials that are explicitly characterized by their non-conductive nature. This specific attribute of non-metallic conduit makes it the preferred choice when insulation from electrical conductance is necessary.
