What does HRC imply in the context of cable? Jacket for CMR Cable “Communications Multipurpose Cable, Riser” is the abbreviation for CMR cable. It is a fire resistance rating for cable jackets as described in NEC Article 800. CMR cable is also known as “riser-rated cable” since it is meant to prevent flames from spreading between floors through risers or vertical shafts.
What exactly is a CL2X cable? Limited-use cables of Types CL2X and CL3X should be labelled as such and shall be classified as acceptable for use in residences and raceways, as well as being resistant to flame spread.
How can you determine if a wall is cable-rated? Typically refers to a “in-wall rated” cable that is meant to be securely inserted within a wall. Cables that are certified for in-wall use must have a label printed on the jacket indicating the cable’s rating.

How is plenum air space defined?
Plenum is a term that refers to a distinct room in a structure that is used to circulate air for heating, ventilation, and air conditioning. It is often seen between a structural ceiling and a drop-down ceiling, or under a raised floor.
What does the abbreviation CM CL2 mean?
CL2. A CL2 rating indicates that a cable has passed the necessary NEC test for a high fire resistance grade. The cable’s materials will not catch fire in the event of a rapid surge of up to 150 watts of power, and the cable itself will not transport a flame.
What is the UL 758 standard?
UL 758 is a standard developed by Underwriters Laboratories that addresses Appliance Wiring Material (AWM). It establishes criteria for single- and multi-core insulated conductors used in manufacturing and production equipment, as well as for connecting appliances.
What exactly is CMG cable?
CM/CMG — General-purpose communications cable. It is designed for general indoor usage in line with NEC Article 800.53(E) (1). In the Vertical-Tray Flame Test outlined in the UL 1865 standard, these cables do not spread flame to the top of a tray.
How is plenum-rated cable defined?
Plenum-rated cable has a unique insulation that emits less smoke and burns slowly. Plenum cable is required in all “air handling” spaces. This ceiling is classified as a plenum ceiling, and any wires that pass through it must be plenum certified.
Which is more reliable, Cat5 or Cat6?
Which Advantages Does a Cat6 Ethernet Cable Offer? Cat6 cables, in comparison to Cat5/5e connections, offer more stringent performance criteria and much faster data transmission rates over longer distances. They are more tightly coiled than Cat5 cables, with thicker conductors and sheaths.
How can I determine if a cable is Cat5 or Cat6?
The fastest approach to determine if your home has CAT6 Ethernet wiring is to examine the printing on the cable’s jacket. Ethernet cable is tagged with the category requirements for which it is built. Most likely, it is concealed inside the wall.
What exactly is CCA cable, and why should it be avoided at all costs?
Poor flexibility and bend radius: CCA conductors are fragile and readily break; merely changing a patch panel or faceplate has been reported to cause failures. CCA wires may potentially break off due to their poor tensile strength, which might occur during packing or shipping.
How are a plenum and a duct different?
A plenum is an air distribution box that is directly connected to the supply outlet of the HVAC equipment that warms or cools the air to maintain a suitable temperature in the home. The plenum is connected to the ductwork that distributes warm or cooled air to various rooms in the home.
What use does a plenum serve?
Plenum boxes are often located on each side of the fan or heat exchanger and provide critical functions such as air intake, distribution, and removal. They are the first stop for air after it has been heated or cooled and the last halt before it returns to your air conditioner, heat pump, or furnace.
What is a plenum that is exposed to the air?
Plenum spaces are open areas above or below the floor that serve as air circulation channels. Technically, any ductwork is a plenum space as well.
Is CL2 HDMI required?
If you are, your local code will almost certainly need CL2 cable. If you are just connecting it through a wall from your Blu-ray player to your television, your codes most certainly do not need CL2 (although areas, and inspectors, do differ). Low Voltage wires, such as HDMI cables, provide little risk of spontaneous combustion.
What is the difference between CL and CL2?
Chlorine is a chemical element with the atomic number 17 and the symbol Cl. Cl2 is a two-atom molecule, while Cl3 is a three-atom anion. As a result, Cl3 has a negative charge, while Cl2 is neutral.
What is a High-Definition HDMI cable?
The HDMI Licensing, LLC has tested high-speed HDMI cables (also known as category 2) to function at 340Mhz, the greatest bandwidth presently available through an HDMI connection, allowing them to reliably carry 1080p transmissions.
What does the term “AWM Style” mean?
AWM is a broad category of wire and cable that encompasses a variety of structures. AWM is often utilized in a wide number of applications, including general purpose wire circuits, control circuits, and appliance internal wiring.
What does the term “cable CSA” mean?
CSA. Typically refers to the cross sectional area of a cable.
What exactly is UL style?
Underwriters Facility (UL) is a third-party certification and testing laboratory. Each authorized AWM structure is assigned a unique style number and a style page is created with a few criteria such as gauge size range, insulating material, temperature rating, and voltage rating.
What is the purpose of FT4 cable?
FT4 Cables are suitable for usage in non-combustible structures. In the column where the trade number appears, products that pass the FT6 Horizontal Flame and Smoke Test are called FT6. This test is for cables that must pass the ANSI/NFPA Standard 262-1985 Horizontal Flame and Smoke Test (UL-910).
Is FEP classified as plenum-rated?
Belden plenum FEP cables are UL-listed cables (Type CL2P, CMP) that are developed particularly for use in commercial buildings’ plenum areas where a high temperature rating is required. According to UL, fluorinated ethylene propylene (FEP) has a temperature rating of 200°C.
Is CMG considered a plenum?
Cablek explains the difference between CMP, CMR, CM / CMG, and CMX cables. CMP cables are plenum cables; they are utilized when networking in air ducts is required. They are suitable for both business and residential areas. The most often utilized commercial grade communication cable is CM/CMG.
How do you determine the kind of plenum cable?
On the cable, look for the designation CMP (Communications Plenum Cable), CL3P (Shielded Multi-Conductor Plenum Security Cable), or CL2P (Class 2 plenum cable). Plenum cable is encased in a fire-resistant plastic covering composed of either polyvinyl chloride (PVC) or a fluorinated ethylene polymer (FEP).
Why is plenum cable more costly than coaxial cable?
Plenum cables are required for running wires through plenum areas. Plenum cables are more costly than riser cables because they are manufactured to a higher fire resistant grade.
