When it comes to wiring in residential settings, the very first decision electricians must make which type of wiring to utilize. Determining the proper wiring will make their job easier, and there will be fewer wiring errors, allowing them to finish the job by hand.

Electrical conduit is one of the many important aspects that every electrician should get familiar with. It refers to robust tubing and other forms of wiring covers used to provide and safeguard an electrical wiring conductor’s route.

Electrical Conduit and their Installation:

An electrical conduit is a plastic or metal pipe through which electrical cables are carried. Conduit is frequently utilised in areas exposed to the environment, such as the outer wall surface. It also covers the cables and is suitable for unfinished areas such as attics, underground parking garages, basements, and even outdoor surface installation. At first glance, the electrical conduit may appear to be quite similar to armoured cable wire. Individual wires are wrapped in armoured cables, like in electrical conduit. AC is represented by these cables, which can be used in any exposed location.

A system including a network of electrical conductors is frequently referred to as a conduit. The following are the reasons why conduit systems are installed:

  • To connect the conduit section as needed.
  • To serve as a bridge outlet for a conductor that has been placed.
  • To Create spaces in conductors, especially for taps and pieces.
  • To offer taps for branch tube runs in particular.
  • To bend the hose at a 90-degree angle for the run.
  • To give the conductor access to the future system and maintenance system.
  • To serve as a lighting fixture and electrical device mounting outlets.

Types Of Electrical Conduit:

The materials used to make mechanical stiffness, tube, and layer thickness classify conduit systems. After considering the cost factor, the materials are chosen for strength, durability, and automated protection. Several specific rules must be followed for wiring equipment in hazardous places where prior approval is required.

For residential and commercial lighting, the following conduit types are commonly used.

1.   Electrical Metallic  Tubing (EMT)

Unbending conduits include electrical metal tubes (EMT), a common example. It’s usually constructed of galvanised steel, but it can also be aluminium. Because EMT is thinner and lighter than RMC, it is often referred to as a “thin-wall” conduit. It may also be hard, but with the use of a simple tool known as a conduit bender, it may be readily bent.

The fittings and couplings on EMT are completely fixed with compression-type bolts or setscrews. The tubing is not threaded in the same way that IMC or RMC tubing is. Furthermore, EMT comes in conventional sizes ranging from 1 inch to 1 and a half-inch. Because it is frequently employed in light commercial or residential applications, EMT is most commonly used in exposed indoor wiring.

2.   Rigid Metal Conduit (RMC)

RMC stands for RMC Oversized Galvanized Steel Hard Metal Conduit. Threaded fittings are used to install them. Outdoors it’s commonly used to give damage and security. Structural support is also necessary, particularly for electrical panels, cables, and other hardware. Only 10 to 20-foot lengths of RMC are available for purchase. And it has to have threads on both ends.

This conduit is regarded as one of the most priced electrical wiring options on the market. It does, however, provide increased power and longevity, which is a significant benefit.

3.   Flexible Metal Conduit (FMC)

FMC is also known as “Greenfield,” derived from the inventor’s name. It features a spiral design that allows it to be incredibly flexible. FMC’s adaptability allows it to pass through walls and even other constructions. Standard FMC is typically utilised in dry indoor environments with short run times.

Furthermore, FMC is an excellent option for many situations that require tighter bends and close quarters. Regular conduits will be more difficult to bend due to the latter. Basic flexible conduit installations include light fixtures, attic vents, and water heaters.

4.   IMC (Intermediate Metal Conduit):

The wall of this conduit is thinner than RMC and thicker than EMT, as its name suggests. Conversely, the conduit’s thickness is a barrier between RMC and EMT. This metal conductor can be threaded or unthreaded, and clamp-type fittings can be used. Steel IMCs are commonly used and can be coated.

5.   Liquid-tight Flexible Metal (LFMC)

While LFMC, or liquid-tight flexible metal conduit, is a form of flexible metal conduit with a plastic covering that is utilised with sealed fittings, the parts that make up the full LFMC have made it impermeable. Outdoor equipment uses this metal electrical conduit, such as air conditioner units.

  • Electrical Non-Metallic Tubing (ENT)

This type of non-metallic tubing is used in the electrical industry. ENT is a flexible, efficient protection conduit. Even without the use of specific equipment, it can be bent. But don’t turn it around. Because it can be spun around the barrier without cutting or welding, it is easier to install than an RNC. Special ENT connectors are utilised, which are usually snap-in and not waterproof.

The umbilical cord will be exposed to moisture; liquid-tight flexible non-metallic condensate (LFNC) is also available.

7.   Rigid PVC

Plastic plumbing pipes are similar to rigid polyvinyl chloride (PVC). It’s also fitted with plastic fittings, which are bonded together. After warming in a portable heater box, it can be folded. The conduit assembly can be watertight since the conduit tube and fittings are bonded together. PVC can be buried straight in the ground in various situations. In rusty situations, it is also permitted.

Conduit Fittings:

____Pipes is a manufacturer of electrical conduit pipes and fittings. Our electrical conduit pipes and fittings are PVC following International Pressure Standards and Non-Pressure pipes under international standards. Our clientele prefers electrical conduits because of their high quality and great after-sales service.

Our pipes and fittings meet or exceed international quality standards. ____ Electrical Conduit Pipes are without a doubt among the best in Pakistan. Our pipe manufacturing services in uPVC pipes, PPRC pipes, MDPE pipes, HDPE pipes, and Electrical Conduit pipes are among the best in Pakistan. For conduit Fittings, we use:

  • Sockets
  • Bends
  • Junction box
  • Saddle clamps

Threaded Vs Screwed Fittings:

Threaded Fittings:

Threaded fittings are used in the majority of pipe applications, and their connections may be easily identified between:

  • NPT
  • BSPT

The taper angle is the main distinction between these two. The NPT system uses a 60-degree thread taper angle, whereas the British Standard Pipe Thread (BPST) fittings use a 55-degree taper angle. These systems define straight pipe thread fittings, which do not rely on a taper to seal against pressure loss or leaks, in addition to tapered threaded pipe fittings. In most cases, a proper sealant is required to ensure that the joint or connection’s seal integrity is maintained. Although most threaded pipe fittings are constructed with right-hand threads, some are available with left-handed (LH) threads.

Screwed Fitting:

Internally threaded screw fittings are common. The exception is the street fitting, which has one exterior thread and one interior thread in the case of a basic elbow. Pipes can be threaded in the field with ease. Teflon tape or pipe compound can join threaded pipes and fittings. To avoid introducing any impurities into the pipeline during joint assembly, it is advised that the compound be applied exclusively to the external thread.
