What is CL2 rated speaker wire?
CL2: This is a cable jacket fire resistance rating defined in Article 725 of the National Electric Code. It stands for “Class 2 Remote-Control, Signaling, and Power-Limited Circuits” cable, which indicates that the cable is suitable for in-wall installation and use for certain low-voltage applications.
Is CL2 outdoor rated?
Outdoor cabling is typically rated CL2 or CL3. For outdoor wires, CL2 should be the bare minimum UL rating of your cables. CL2 and CL3 cabling is also typically rated for installation in walls or ceilings so you can have a concealed installation throughout your house.
What is a 16 4 wire?
The 16/4-GY is a 16 gauge 4 conductor multi-conductor cable designed for security and low power applications. This 16-4 cable features bare copper stranded conductors, a gray PVC jacket, and a CMR rating. Solid bare copper strands are used to create the four color coded 16 gauge (AWG) conductors.
Is speaker wire plenum rated?
Plenum speaker wire is CMP-rated for installation in plenum air spaces, such as drop ceilings. Our professional-grade speaker wire is comprised of oxygen-free copper conductors, ensuring that it delivers audio signals with the highest fidelity.
How do you measure speaker wire size?
Speaker Wire Gauge The thicker the wire the lower the gauge number & the thinner the wire the higher the gauge number or AWG. For example, a 12 AWG is thicker than an 18 AWG wire. The most common audio speaker wires are 12 Gauge, 14 Gauge, 16 Gauge, and 18 Gauge.
What is CL2 and CL3 wire?
CL2 is the designation for Class 2 Circuit wire and CL3 is the designation for Class 3 Circuit wire. Both are regulated under NEC Article 640, 725 & 820. They are both used for Video, Audio Interconnects, remote-control, signaling, and power-limited circuits.
What is CL2 rated HDMI cable?
A CL2 rating meaning that a cable has passed the required NEC test for a high rating of fire resistance. This rating is most commonly found on our copper cables such as our HDMI cables, Bare Copper Wire, VGA, DVI and Coaxial cables.
What is the difference between CL2 and CL3 wire?
The difference between the two is that CL2 is rated for up to 150 volts while CL3 is rated for up to 300 volts. (NEC 725.71 F) According to NEC 725.2, CL2 offers some protection from electric shock while CL3 offers a bit more because it is rated to carry more voltage.
What does CL2 wire mean?
Class 2 Circuit
CL2 is the designation for Class 2 Circuit wire and CL3 is the designation for Class 3 Circuit wire. Both are regulated under NEC Article 640, 725 & 820. They are both used for Video, Audio Interconnects, remote-control, signaling, and power-limited circuits.
Do I need CL2 or CL3?
The main difference between the two is the wattage that a CL3 rated cable can carry. While CL2 cables can carry a surge of up to 150 watts, and CL3 can carry twice that at 300 watts. A CL3 rated cable can take the place of any CL3, however, a CL2 cannot take the place of a CL3.
What is the difference between Cl2 and CL3 cable?
These ratings refer to use in low-voltage applications; you’ll also see cable with CL2 and CL3 ratings, which refer to the amount of voltage the cables can carry (CL2-150 volts, CL3-300 volts). CL2 and CL3 cable doesn’t reduce smoke or gases, but minimize the possibility of shock.
What is the difference between CMR and Cl cables?
CMR: This is the next step up. A CMR rating means the cable can be used in the risers of commercial buildings because they limit the spread of flames better than cables in the CL/CM family.
What do the voltage ratings on electrical cables mean?
You can install these rated-cables in the wall or ceiling, and don’t have to worry about things like risers and plenums in home use. These ratings refer to use in low-voltage applications; you’ll also see cable with CL2 and CL3 ratings, which refer to the amount of voltage the cables can carry (CL2-150 volts, CL3-300 volts).
What is the difference between CLCL/cm/CMG cable jackets?
CL/CM/CMG: These cable jackets are suitable for use in all ordinary situations, with CL cables used for audio/visual applications and CM/CMG used for communications applications like Ethernet.
