CL2. A CL2 rating meaning that a cable has passed the required NEC test for a high rating of fire resistance. The cable’s materials are not going to burn during a sudden surge of electricity up to 150 watts and the cable itself will not carry a flame.

What is CL2 rated?

CL2. A CL2 rating meaning that a cable has passed the required NEC test for a high rating of fire resistance. The cable’s materials are not going to burn during a sudden surge of electricity up to 150 watts and the cable itself will not carry a flame.

What is CM cable rating?

CM stands for “Communications Multipurpose.” It is a cable jacket fire resistance rating defined in Article 800 of the NEC. In the case of CM, the standard outlines general use, or use in cases where the fire code does not place any restrictions on cable type.

How do I know if my Ethernet cable is outdoor rated?

Outdoor-rated cables go through additional testing such as a cold-bend test where the cable will be kept at a temperature such as -20C for 4 hours while bent in a pre-determined radius. If the cable does not crack it passes.

What is Riser Rated?

Riser Cable Riser rated cables run between floors through cable risers or in elevator shafts in non-plenum areas. These cables must also self extinguish and prevent the flame from traveling up the cable in a vertical burn test. Fire requirements are not as strict on riser cables compared to plenum cables.

What is difference between Cl and CL2?

Chlorine is a chemical element having the symbol Cl and atomic number 17. Cl2 is a molecule consisting of two atoms whereas Cl3 is an anion consisting of three atoms. Hence, Cl3 has a negative electrical charge, but Cl2 is neutral.

What does CL2 stand for?

What is CL rating on wires?

The CL rating indicates that the cable is intended for wiring typical of audio and video signal types such as speaker wire or HDMI cable. CL with either a 2 or 3 suffix designates that the cable is intended for class-2 or class-3 circuits and can be run within walls of buildings or dwellings.

Is CL2 wire plenum rated?

CL2 cables may be further classified as “CL2R” (Riser Rated) and CL2P (Plenum Rated). For a more detailed explanation of Riser and Plenum ratings, see “CMR” and “CMP” below. CL3: CL3 stands for “Class 3” wire and is also defined in Article 725 of the National Electric Code.

Is CL2 wire shielded?

Superior shielding of RG-6/U includes two layers of aluminum foil and braid layer shielding to provide 95% coverage, enhanced performance, and protect against EMI electromagnetic noise. The CL2 (Class 2) residential fire safety rating, allows for installation of the cable behind walls.

What’s the difference between CL2 and CL3 wire?

In plain English that means that CL2 and CL3 are types of multi-purpose wire used for things like security systems, speaker wire, intercom systems, nurse call buttons, and more. The difference between the two is that CL2 is rated for up to 150 volts while CL3 is rated for up to 300 volts.
