Allied Encyclopedia: Cat 8 Cable

What is Cat 8 Cable?

Cat 8 cable, or category 8 cable is a shielded, copper twisted-pair communications cable. It is the latest ratification of twisted cable systems, which was implemented under ANSI/TIA 568-C.2-1. The International Organization of Standards (ISO) equivalent is expected to ratify in either 2017 or 2018. Cat 8 cable can be used to link Television, computer data, video, audio, and various other data systems to a given data center. While Cat 8 offers high speeds and strong connections, it is relatively short ranged and designed for use in data centers, not office wiring and connection. To reiterate, Cat 8 can be used to strengthen a data center’s performance levels significantly with a bandwidth four times larger than Cat 6A. On the other hand, it would not be practical to wire an office’s phones or computers due to its length limitations. All other category cables have a length of 100 meters compared with Cat 8’s 30 meter length. Cat 8 is divided between two classes, class I and class II, or Cat 8.1 and Cat 8.2. The differences between the two being shielding types and connector compatibility.

Allied Encyclopedia: MTW/TEW Wire

What is MTW/TEW Wire?

MTW/TEW wire is UL rated Flexible Machine Tool Wire. MTW stands for Machine Tool Wire and TEW stands for Thermoplastic Equipment Wire. The UL ratings are UL 1028, UL 1283, UL 1284 and UL 1015.
MTW/TEW cable is used in machine tool applications. These include switchboards, appliances, electronic circuits, control cabinets and the wiring of machine tools. MTW wire passes the VW-1 flame test and is also moisture resistant. This article will examine two types of MTW/TEW wire which is available with either a tinned copper and bare copper conductor.

TEW / MTW Wire Construction
TEW/MTW wire is available with conductors that are tinned copper hook up wire or stranded bare copper hook up wire. It is used primarily in the wiring of machine tools and control cabinets, electronic circuits and switchboards. This wire is UL 1028, UL 1283, UL 1284 and UL 1015 rated. This wire features PVC (polyvinylchloride) insulation which makes it resistant to heat, moisture and oil. TEW cable is available with a variety of wall thicknesses, weights and sizes.

UL Ratings

MTW and TEW have dual UL ratings. This simply means that the wire meets more than one industry standard. The most common UL ratings for these wires are UL 1028, UL 1283, UL 1284 and UL 1015.

Wire Size Conductor Temperature Rating Voltage Rating Min. Average Thickness
UL 1028 22 AWG-6 AWG Solid or stranded

Tinned or bare copper

105°C 600V 22-8 AWG/ 45 mils

7-6 AWG/ 60 mils

UL 1283 8 AWG-1000 MCM Solid or stranded

Tinned or bare copper

105°C 600V 60 mils
UL 1284 8 AWG-2 AWG Solid or stranded

Tinned or bare copper

105°C 300V 80 mils
UL 1015 30 AWG – 2000 MCM Solid or Stranded 105°C 600 V 30-9 AWG/ 30 mils

8-7 AWG/ 45 mils

6-2 AWG/ 60 mils

1-4/0 AWG/ 80 mils

250-500 MCM/ 95 mils

550-1000 MCM/ 110 mils

110-2000 MCM/ 125 mils

There are several characteristics of the wire that influence the UL rating. With these specific styles, a wire that is 8 AWG could possibly be approved as UL 1028, UL 1283, or UL 1284 ratings. However, a wire that is 2 AWG could only have UL 1283 or UL 1284 ratings. Another characteristic that can determine which UL ratings a wire could be approved as is the minimum average insulation thickness. A wire that is 6 AWG would overlap UL 1028 (60 mils), UL 1283 (60 mils), and UL 1015 (60 mils), and could potentially be dual rated as all three styles. However a wire that is 4 AWG would not be able have both ratings because the insulation thicknesses are 60 mils vs 80 mils.These thicknesses are not the same for both styles.  MTW/TEW wire also can have other dual ratings such as SAE 1127, Type SGT rating which are controlled by other organizations such as NEMA or SAE. A UL 1284 wire with a bare copper conductor in sizes 6 AWG to 4/0 can be dual rated as SAE 1127, type SGT, since the requirements of both styles overlap. For more information on dual ratings, check out our Allied Encyclopedia article on this topic.

While the above paragraph gives a full overview of how dual ratings can work, within the wire and cable industry, there are some very common dual ratings.  The chart below covers the most common dual ratings according to industry standards for MTW wire.

Main UL Rating Size
UL 1015 10 AWG and smaller
UL 1028 8 AWG
UL 1283 6-2 AWG
UL 1284 1 AWG and larger
BC5W2 Tinned: 6 AWG -4/0

Bare: 6 AWG – 750 MCM

There is also the BC5W2 rating for wires sized 6 AWG- 4/0 tinned and 6 AWG – 750 MCM bare.
