Metal, plastic, or fibre conduits are used in electrical systems to protect cables and wires. In almost every household and commercial organisation, they are used, particularly for wire that is installed outdoors or that is exposed. The fragile nature of electrical wires and the potential dangers they pose when damaged led to the creation of the electrical conduit.
The material used to create the tube, the mechanical stiffness, and the wall thickness are utilised to categorise different types of conduit systems. After taking the cost into account, the material is chosen for its ability to resist corrosion and mechanical damage. The primary reason conduit bodies are employed in the electrical wiring system is to protect the wiring from environmental factors, both natural and man-made. They are simple to access and resistant to heat, fire, and dust.

FACTS ABOUT ELECTRIC CONDUIT
SURFACE CONDUIT WIRING
Surface conduit wiring refers to the installation of conduits on the surface of a wall or roof. The first holes for this kind of wiring are drilled into the wall in a straight line at equal intervals. After that, rowel plugs are inserted in these holes and saddles are attached above them using screws. Conduits are then put in place above it. The number of wires that will be run through the conduit determines its size when utilised for this form of wiring. Furthermore, fittings will be utilised that are the same size as the conduit that is used for wiring.
CONCEALED CONDUIT WIRING
Concealed conduit wiring is a type of wiring in which the conduit is hidden by creating grooves in the wall, which are subsequently plastered over. It is known as concealed conduit wiring because only switches and lamp holders are visible from the outside on this sort of wiring. In other terms, concealed wiring refers to wire that is installed inside a pipe that is part of a wall. Plaster is applied after the pipe has been installed and grooves have been created on the wall for the concealed wiring. Only a few junction box locations are still visible, from which wiring may be maintained and fixed. Conduit pipes are firmly fastened to the walls using hooks before being plastered.
SAFETY
Poorly managed electricity can cause harm or loss in a variety of ways. However, electrical conduit keeps electrical wires from coming into contact with conductive or combustible materials. Electrical conduit provides an armoured path for audio, video, telephone, and internet cable as well as a secure ground path for electricity.
NEED NOT BE FREQUENTLY REPLACED
When purchasing a property or adding on, an inspector will typically check the structure to make sure it is “up to Code,” making the buyer and seller aware of any flaws or safety code violations. This is because wiring that is improperly installed, worn out, or old might ignite a fire when it overheats or generates a spark. Older homes may need new wiring or safety systems even if they have previously passed inspections, depending on the criteria. Since existing conduit can be used to enhance the electrical system, conduit is frequently not replaced. Electrical conduit with a large diameter offers alternatives for future improvement.
INSTALLING CONDUITS
A variety of connectors would be needed to install a electric conduit system. Conduit “sticks” can be connected together with the use of conduit connectors to create a long, straight route. Furthermore, they join conduits to bends that were constructed on site. Different conduit types call for varied connector types as well.
Conduit fittings come in a wide range of shapes, sizes, and materials, and they’re typically used to join conduit runs together as well as to connect the ends of conduit to boxes, enclosures, or electrical equipment. To connect conduits to boxes or enclosures of various sizes and when the direction of the majority of metallic conduits needs to be changed, fittings are required. Additionally, there are straps and clamps that are utilised to fasten and add to the support of conduits.
If a conduit run is likely to be exposed to moisture, fumes, or dangerous circumstances. you might need to employ certain types of fittings. PVC pipe manufacturers are one of the mostly opted choice for these type of fittings
