Conduit
Conduits are tubings used to protect and guide electrical wires. They are made of materials such as plastic, steel, galvanised steel, nylon, PVC, PP, and steel spring wire. Conduits are especially protects exposed wires in open areas, underground, or inside walls.
Differenttypes of electrical conduits
Some common acronyms and terms used when discussing different types of conduits include "rigid" and "flexible." The main types are:
- Electrical conduit
- Flexible conduit
- Metal conduit
These three categories are further divided into specifictypes of conduits, including:
- IMC (Intermediate Metal Conduit): A sleeker, lighter version of RMC that is often accepted for the same uses as RMC.
- RMC (Rigid Metal Conduit): One of the most durable types of electrical conduits, made of galvanised steel. Has excellent protection and can support boxes, cables, and other electrical equipment.
- EMT (ElectricalMetallicTubing):A thinmetaltube that is easy to bend and twist using aconduitbender. It can be cut with a small or 12V reciprocating saw with a high TPI blade.
- FMC (Flexible Metal Conduit): Has a spiral shape that allows it to flex over short distances. It is useful for adding conduits in tight spaces or around existing equipment.
- LFMC (Liquid-Tight Flexible Metal Conduit): Similar to FMC but has a waterproof covering, suitable for use in outdoor areas.
- ENT (Electrical Non Metallic Tubing): A flexible PVC conduit tubing that can be used in place of EMT and run behind walls and encased in concrete. It has a 2-hour fire resistance rating but is not UV-resistant.
- RigidPVC:Heated and bent before use. It is watertight when properly installed and has the same properties as a waterpipeas anelectrical conduit.
- Galvanised Iron (GI) conduit: A type of electrical conduit made from a mixture of iron and zinc, with a protective coating of galvanisation. Commonly used in electrical installations for the protection and routing of electrical wiring.
Advantagesof electrical conduit
- Safe and reliable wiring: Electrical conduits provide a safe and secure path for electrical wires. It encloses and protects the wires from damage that occurs if they are left exposed.
- Conveniently used in humid places: Electrical conduits are made of materials that are resistant to moisture and humidity. Good for use in damp or humid environments, such as bathrooms and kitchens.
- Long-term usage: Electrical conduits are durable, ideal for use in long-term installations. It can withstand the wear and tear of daily use over time.
- Easy to install: Electrical conduits are relatively easy to install. It can be cut to size and bent to fit around corners - a versatile choice for a wide range of applications.
- Cost-effective: Electrical conduits are affordable. It is widely available and good for both residential and commercial installations.
