ENT stands for Electrical Nonmetallic Tubing, also known as smurf tube. It is a flexible, moisture-resistant raceway designed for electrical conductors. ENT is defined by specific construction and installation requirements, permitted uses, and prohibited applications. ENT is commonly used for low-voltage wiring and, in some cases, for higher-voltage applications. However, it is rarely used for outdoor electrical wiring and has limited approved uses in some jurisdictions.

What You'll Learn
ENT is an acronym for Electrical Nonmetallic Tubing
The National Electrical Code 2011 allows ENT to be used for running 120V electrical wire. However, its use is often confined to low-voltage wiring, and some localities forbid its use for 120V electrical purposes. ENT is commonly used for data communication systems, such as ethernet and phone lines.
The specifications and guidelines for the use and installation of ENT are outlined in Article 362 Wiring Methods and Materials, Electrical Nonmetallic Tubing: Type ENT of the NFPA 70 code. This article details the permitted and prohibited uses of ENT, as well as the construction and installation requirements. ENT is permitted for use in buildings up to three stories high and in concealed locations. However, it is prohibited in hazardous areas and direct earth burial.
It is important to note that flexible ENT is not permitted in all jurisdictions and is generally not used for exposed electrical work. Proper installation of ENT involves securing and supporting it, making correct bends, and ensuring joints are made correctly. Construction specifications, marking requirements, and grounding practices must also be followed for safety and compliance.

ENT is flexible, moisture-resistant, and designed for electrical conductors
ENT stands for Electrical Nonmetallic Tubing. ENT is a flexible, moisture-resistant raceway designed for electrical conductors. Its flexibility is due to its construction from plastic, which is easier to cut than metallic conduit products. This plastic conduit can be heated and bent into non-standard shapes, or pre-formed bends and elbows can be used.
The flexibility of ENT makes it a good choice for exotic cabling where the right rating isn't available to meet the code. It is also used for both 120V/240V and data wiring in some countries. However, it is not suitable for outdoor use or exposed electrical work.
As a non-metallic tubing, ENT is moisture-resistant. This makes it suitable for use in basements or crawl spaces where moisture in building interiors is a concern. It can also be used in buildings up to three stories high and in concealed locations. However, it is not permitted to be used in hazardous areas or for direct earth burial.
The use of ENT requires specific construction and installation requirements, including proper securing and supporting, making correct bends, and ensuring joints are made appropriately. It is important to note that ENT is not permitted in all jurisdictions, and licensed electricians are usually required for its installation.

ENT is used for low-voltage wiring
ENT stands for Electrical Nonmetallic Tubing. It is a type of conduit that is made from flexible plastic and is often used for low-voltage wiring applications.
Electrical Nonmetallic Tubing (ENT) is a flexible, moisture-resistant raceway designed for electrical conductors. It is made from materials such as PVC or ribbed plastic and is joined using specific conduit solvent cement. ENT is defined by specific construction and installation requirements, permitted uses, and prohibited applications. For instance, ENT is permitted for use in buildings up to three stories high and in concealed locations, but it is prohibited in hazardous areas and direct earth burial.
ENT is commonly used for low-voltage wiring, including data communication systems, alarms, and audio/video applications. Its flexibility allows it to be bent to non-standard shapes, making it suitable for running wires through walls and floors. ENT is also used for phone and data wiring, as well as for exotic cabling where the right rating is unavailable to meet the code.
While ENT is suitable for low-voltage wiring, it is important to note that it is not permitted for exposed electrical work in most jurisdictions. Additionally, its use for 120V electrical wiring is confined to specific localities, as some forbid its use for this purpose.
Overall, ENT is a versatile option for low-voltage wiring applications, providing flexibility and moisture resistance for electrical conductors. However, it is important to refer to local codes and regulations to ensure compliance and safety.

ENT is not suitable for exposed electrical work
ENT stands for Electrical Nonmetallic Tubing. It is a flexible, moisture-resistant raceway designed for electrical conductors. While ENT has its advantages, it is not suitable for exposed electrical work.
Firstly, ENT is not suitable for exposed electrical work because it is not permitted in all jurisdictions. The National Electrical Code of 2011 allows ENT to be used for running 120V electrical wire, but some localities forbid its use for this purpose. This is likely because ENT is susceptible to combustion, which can result in toxic byproducts or excessive smoke generation. As such, ENT is prohibited in hazardous areas.
Secondly, ENT is not typically used for exposed electrical work because it is confined to low-voltage wiring. ENT is commonly used for communications, alarms, audio/video, and phone/data wiring. This type of wiring is usually concealed within poured walls, floors, and buildings. ENT is also not suitable for outdoor use, as weatherproof boxes require a pre-wired liquid-tight electrical conduit whip to connect outdoor electrical equipment exposed to the weather.
Thirdly, ENT may not be suitable for exposed electrical work because it requires specific construction and installation methods. For example, ENT sections and fittings are joined by conduit solvent cement, which is specifically formulated for use with PVC. If other types of cement are used, it can compromise the safety of the installation. ENT also requires proper bends and correctly made joints to ensure safety and compliance.
Finally, ENT is not suitable for exposed electrical work because it is not as versatile as other options. For example, ENT cannot be bent using an open flame, which may be required for certain installations. In some cases, a licensed electrician is required to install electrical wiring, and they may prefer to use other types of electrical conduit that are more familiar or readily available. Overall, while ENT has its applications, it is not suitable for exposed electrical work due to safety concerns, code restrictions, and installation requirements.

ENT is joined with PVC cement
ENT stands for Electrical Nonmetallic Tubing, which is a flexible, moisture-resistant raceway designed for electrical conductors. It is primarily used for low-voltage wiring, such as communications, alarms, and audio/video systems, although it can also be used for 120V and 240V wiring in certain cases.
When joining ENT with PVC fittings, it is important to note that dedicated ENT fittings are designed to snap onto ENT, so cement is not typically required. However, in some cases, cement may be desired for added security. If you choose to use cement, it is important to follow the manufacturer's instructions carefully to ensure proper installation.
Carlon, a manufacturer of ENT and PVC fittings, states that their products can be used together with PVC cement. Specifically, they recommend using their Flex-Plus Blue ENT product with Schedule 40 fittings (couplings and adapters) in sizes ranging from 1/2" to 2". It is important to follow the specific cementing instructions provided by the manufacturer for a secure and safe installation.
While some electricians have reported success in using PVC cement to join ENT and PVC fittings, others have noted that the solvent cement can weaken the ENT over time, leading to cracks and brittle connections. Therefore, it is essential to carefully consider the manufacturer's instructions and guidelines, as well as local building codes and regulations, before deciding whether or not to use cement when joining ENT with PVC fittings.
In conclusion, while it is possible to join ENT with PVC cement, it is important to weigh the benefits against the potential drawbacks. Dedicated ENT fittings that snap into place may provide a more secure and reliable connection, especially if proper installation techniques are followed. Consulting with a professional electrician or contractor can help ensure that the chosen method complies with safety standards and is suitable for the specific application.
