What Is The Difference Between A PVC Pipe And Conduit?

While PVC pipes and conduits are often confused due to their similar appearance and material composition, they serve distinct purposes and should not be used interchangeably. Understanding the key differences between the two is essential for selecting the right component for your specific application.

Pressure Capacity

One of the primary distinctions lies in their pressure ratings. PVC pipes are specifically designed for plumbing applications and are tested to withstand water pressure. The pressure rating is typically printed on the pipe itself, ensuring that it can handle the demands of fluid transportation without failure.
In contrast, PVC conduits do not require pressure ratings since they are intended for electrical wiring rather than fluid flow. Using PVC conduits for plumbing can lead to significant issues, including leaks and potential electrical hazards, as they are not engineered to handle pressure.

Colour

Colour is a quick and easy way to differentiate between PVC pipes and conduits. PVC pipes are generally white, a colour associated with plumbing and water transport. On the other hand, PVC cable conduits are typically black or grey, aligning with their role in electrical installations.

Wall Thickness

The wall thickness of PVC pipes is greater than that of conduits. This increased thickness ensures that PVC pipes can withstand the physical stress and pressure associated with plumbing applications. The robust walls prevent bending and ensure the pipe remains intact even under high-pressure conditions.

PVC conduits have thinner walls to allow for flexibility and ease of installation in electrical systems. Despite the reduced thickness, PVC conduits provide ample protection for wiring, balancing durability with the need for flexibility during installation.

UV Degradation

PVC conduits are often installed outdoors, where they are exposed to UV rays and sunlight. To combat potential degradation, many PVC conduits are UV-stabilized, allowing them to withstand prolonged sunlight exposure without cracking or becoming brittle.

Conversely, PVC pipes are typically installed indoors or underground, where they are shielded from direct sunlight. As a result, they are not UV-stabilized and can degrade if exposed to ultraviolet rays, making them unsuitable for outdoor use.

Connections And Placement

The methods for connecting PVC pipes and conduits also differ. PVC conduits feature flared openings that allow for easy attachment without the need for couplers. Specialized conduit clips can be used to secure them, but these clips are not compatible with PVC pipes.

On the other hand, PVC pipes often require couplers and cement to join sections together securely. These materials are specifically designed for plumbing applications and are incompatible with conduits, underscoring the importance of using each component for its intended purpose.

What Are Plastic Conduit Fittings, And How Do They Work?

To create a functional and reliable conduit system, plastic conduit fittings are essential. These fittings play a crucial role in connecting conduit sections, attaching conduit to electrical devices, and providing additional support to ensure the system remains secure and efficient.

Conduit Bodies

Conduit bodies are tubular fittings with openings at both ends, facilitating seamless bends and connections within the conduit system. Available in various sizes and designs, these fittings allow for easy placement and adjustment of conduits during installation. Clear labeling on conduit bodies helps identify the correct type and size needed for specific sections of the system.

Conduit Clips

For long runs of conduit, additional support is necessary to prevent sagging or breaking. Conduit clips and clamps are mounted on walls or ceilings using bolts or screws, securing the conduit in place. It’s important to adhere to regulatory and safety codes when selecting the appropriate size and type of conduit clip to ensure maximum support and compliance.

Conduit Couplings

Conduit couplings are used to join multiple conduits, creating a continuous and integrated network. While PVC tubing can sometimes be connected without couplings using belled ends, couplings are essential in sections where conduits have been cut or need to be joined. Available in various sizes and often featuring internal threading, conduit couplings ensure a secure and stable connection between conduit sections.

How Do You Run Cables And Wiring In Conduits?

Installing cables and wires within conduits can be challenging, especially when navigating bends and tight spaces. Here are some effective methods to streamline the process:

The String Method

The string method is ideal for short, straight conduit runs. This technique involves pushing a rod with a string attached through the conduit. Once the rod reaches the end, you can pull the string back, bringing the wire along with it. This simple method is effective for straightforward installations without complex bends.

A Conduit Piston

A conduit piston, sometimes referred to as a conduit mouse, is a specialized tool designed to pull wires through conduits. By attaching the wire to the piston and creating a vacuum, the piston propels the wire along the conduit. This method is particularly useful for conduits with multiple bends and twists, though it’s best suited for shorter runs where precise control is needed.

The Fish Tape Method

Fish tape is a standard tool in electrical work, consisting of a long, flat metal wire wound around a spool. To use this method, you feed the fish tape through the conduit and attach the electrical wire to the end. By pulling the tape back through, the wire is guided through the conduit. This method is versatile and works well for various conduit lengths and configurations.

What Type Of Wiring Is Run Through Cable Conduits?

Cable conduits are designed to accommodate a wide range of wiring types, but certain wires are particularly well-suited for conduit systems. The most common types include THWN and THHN wires:

THWN Wires

THWN stands for Thermoplastic Heat and Water-resistant Nylon-coated. These wires feature thermoplastic insulation that provides excellent resistance to heat and moisture, making them ideal for environments where exposure to water or high temperatures is a concern. The nylon coating adds an extra layer of protection, enhancing the wire’s durability and longevity within conduits.

THHN Wires

THHN stands for Thermoplastic High Heat-resistant Nylon-coated. Similar to THWN wires, THHN wires have thermoplastic insulation but offer even higher heat resistance. They often come with an additional nylon coating, providing superior protection against environmental factors. THHN wires are commonly used in both residential and commercial electrical systems, making them a versatile choice for conduit installations.

Modern electrical installations typically require a grounding wire to ensure safety and compliance with electrical codes. While non-metallic cables require a separate grounding wire, metal conduits can sometimes serve this purpose, eliminating the need for additional components. However, it’s essential to verify current electrical standards, as older fittings may have different requirements.
