What is thwn-2 wire?
Description TW/THW is a solid or stranded, soft annealed copper conductor insulated with Polyvinylchloride (PVC). It is UL rated for 600 volts. #10, 12, and 14 AWG are 19 strands, all others are “highly flexible” stranding constructions. Canadian Standards Association (CSA) listed AWM-IA (Class I Group A) and TEW products are 600 V FT-1 rated.
What is direct burial cable?
What Is THW Wire? This one stands for thermoplastic, heat- and water-resistant wire. This acronym is missing the “N” for nylon-coated. The nylon coating looks like a little piece of plastic over a shoelace and protects the wire in a similar fashion.

MTW and TEW Wire Construction
As stated above, the main difference between these two wires is their conductor. While the tinned conductor provides greater corrosion resistance, it can be affected by humid environments, making it more ideal for dry locations. Both types of wire feature Polyvinyl Chloride (PVC) insulation.
UL Ratings
Both MTW and TEW wire are often dual-rated wires. This means that a wire may meet more than one industry standard. Common standards for MTW and TEW wire include UL AWM Styles UL 1028, UL 1283, UL 1284, and UL 1015. There are many specifications for each rating, including AWG size, insulation thickness, and voltage rating.
What is THHN wire?
THHN wire is covered with a PVC jacket and nylon coating. This wire is a bare one conductor copper wire and is often used indoors or in conduit. The most popular sizes for THHN wire are 12 and 4/0, though other sizes are available for nonstandard projects.
What is the most common type of wire?
The most common types of electrical wire are THHN, Romex, and UFB wire. However, in order to understand which electrical wire will do the best job for a specific project, it’s best to know the capabilities of each kind of wire. THHN Wire. THHN wire is covered with a PVC jacket and nylon coating.
What is a romex wire?
Romex Wire. Romex wire is made out of two or three THHN wires combined with a grounding bare copper wire. Like the THHN wires, Romex wire can’t be used outside because of its minimal PVC jacket protection.
Can you use Romex wire outside?
Because of the ‘bare essential’ nature of this wire however, it isn’t recommended for outside use. Romex wire is made out of two or three THHN wires combined with a grounding bare copper wire. Like the THHN wires, Romex wire can’t be used outside because of its minimal PVC jacket protection.
What is THWN wire?
THHN, or thermoplastic high-heat resistant nylon-coated wire is most often used for connecting appliances and branch circuits. THWN or THWN-2, as it’s sometimes referred to when dual-rated, ...
What is the material of a wire?
Wire material: Aluminum or copper. Conductors: Can be solid or stranded, depending on the size. Jacket: Nylon outer jacket with a polyvinylchloride (PVC) insulation. The nylon jacket is essential for mechanical protection and protection from abrasion when the wire is fished through conduit.
What is the best wire for building?
If you’re in need of a building wire that is strong and effortlessly handles heat, there’s no doubting that THHN wire is the route to go. However, using this type of cable comes with a number of other additional advantages: 1 Handles high voltages. THHN wire can manage up to 600 volts. Its copper conductor allows it to handle such high voltages without any issues. 2 Wet and dry application. With the existence of the dual-rating, you are not limited on the environment it can be installed in. Most THHN wires can now be used in settings that are both wet and dry. 3 Durability. The strong jacket makes it resistant to damage and abrasion. 4 Affordability. THHN is a very cost-effective choice for building wire. You can often find many deals by just simply searching the internet. It’s much more affordable than XHHW building wire. 5 Can save you energy and time. The flexible nylon coating makes THHN very easy to manipulate and install. 6 Simple application. THHN wire comes color-coded making it very easy to install. 7 Comes in a variety of different sizes. Possibly one of the greatest advantages of this type of building wire is that it comes in a wide variety of sizes. You are sure to find the perfect size to fit your project needs.
What is a THHN cable?
THHN is the original version of the now dual-rated cable. Previously it was only meant to be used for dry applications.
Is THHN wire toxic?
The thermoplastic outer jacket of THHN wire has been known to release toxic gases when burned . It is strongly urged that these wires are positioned within conduits to prevent the release of any toxic materials.
What is XHHW-2 wire used for?
On the other hand, XHHW-2 is the next generation of the XHHW wire. Although its primary use is for commercial and industrial buildings, it is also often used in raceways, circuit, and feeder wiring. XHHW-2 is permitted for use up to 600V and is suitable for both wet and dry locations up to 90 degrees Celsius.
What is nylon jacket?
The nylon jacket is essential for mechanical protection and protection from abrasion when the wire is fished through conduit. Also, the jacket helps prevent exposure to any hydrocarbons like gasoline, grease or other oils.
