Non Metal Conduits Essay

Different Types of Non-Metal Conduits
Non-metal conduits are low cost and durable electrical pipes that protect the wiring in residential and commercial buildings. The conduits do not allow ingress of water or suffer from corrosion compared to some types of the metallic conduits. For this reason, they can be used in a variety of environments including the wet and corrosive areas.
Although they do not provide a high degree of mechanical protection against heavy weights or impacts, the non-metal conduits are adequate for general applications. For this reason, they are commonly used within the walls, above the ceilings, buried in the concrete during construction and even used for underground cabling in areas where there is no risk of excessive pressure.

This makes the installation and fitting of the PVC non-metallic conduit very easy, quick and less expensive since it requires fewer couplers and bends.
PVC conduit is the most common type for residential and commercial installations. It is usually available in three main wall thickness or gauges. The lightest wall is suitable for embedding in the walls or above the ceilings during construction or upgrades. Applications such as underground cabling and others that require more strength may use the medium or heavy duty PVCs depending on the amount of pressure they exert on the conduits.
Fiberglass reinforced epoxy (FRE)
This is a lightweight nonmetallic conduit that is less costly, easy to work with and suitable for both indoor and outdoor applications. It is also referred to as reinforced thermosetting resin conduit (RTRC) or simply as fiberglass conduit. Just like the other conduits, it is usually available in different wall thicknesses to cater for a variety of environments and
