Seven Most Common Types of Electrical Conduit NZ in Use

Electrical Conduits are nothing but some durable tubing or any other type of enclosures used frequently to provide a correct routing and for protection of the individual electrical wiring conductors. These conduits are normally required where wiring is exposed and is prone to damage. Electrical conduits could be made of metal or plastic and could be rigid or flexible. The conduits easily available at the electrical store in Auckland can be fixed and installed in electrical circuits with compatible fittings (couplings, elbows, connectors) and electrical boxes, usually made of the same or similar material. It’s however advisable that the good quality electrical conduit NZ should be installed by professionals that work in accordance with the applicable local rules.

Currently, following seven types of electrical conduits are used in residential and light commercial wiring and these are:

• RMC – Rigid Metal Electrical Conduit

Rigid metal conduits, or RMC, are long-lasting galvanized steel tubing and suggested for installation with threaded fittings. It is usually used outdoors to safeguard the wirings from any external damage. RMC can additionally offer structural sustenance for electrical cables, panels, and other gears. RMC is sold in 10 and 20-foot lengths with both ends having threads.

• IMC – Intermediate Metal Conduit

Intermediate metal conduit, or IMC, is a much thinner and lighter-weight adaptation of the rigid metal conduit and is being used and preferred for the similar applications as those of RMC. Being lighter in weight, these conduits are more in use in new constructions.

• EMT – Electrical Metallic Tubing

EMT is most commonly made of galvanized steel and sometimes with aluminum. EMT is also called a thin-wall conduit, is robust, and can be twisted effortlessly with a simple tool referred to as a conduit bender. EMT is fitted with couplings and fittings that are fastened with setscrew or compression-type fasteners. It is mostly used for bare indoor wiring that is installed in residential and light commercial construction.

• ENT – Electrical Non-Metallic Tubing

Electrical nonmetallic tubing (ENT) is bendable corrugated plastic tubing and is safe to use since its inflammable and averts moisture. It is extremely flexible and gets installed with snap-lock or can be glued with plastic fittings and is commonly used for indoor applications. In addition, ENT can be fitted inside a concrete block building.

• FMC – Flexible Metal Conduit  

Flexible metal conduit (FMC) comes with a spiral-shaped construction making it supple and possible to pass easily through the walls and other buildings. Normally, this category of electrical conduit NZ is used for indoor locations and covers short distances.

• LFMC – Liquid Tight Flexible Metal Conduit

Liquid-tight flexible metal conduit (LFMC) is a category of flexible electrical conduit Auckland that comes with a plastic coating and is made watertight because of sealed fittings. The most common use of this electrical conduit is for exposed or outdoor equipment like air conditioners.

• Rigid PVC Conduit

Rigid Polyvinyl Chloride (PVC) is almost like the plastic plumbing pipe and can be fitted with plastic fittings. The conduit, being flexible can be bent post-heating and since the tubes and fitting are glued, it becomes water-resistant, making it ideal to be installed in the ground for numerous applications.
