What is the difference between CL2 and CL3 speaker wire?
What is the difference between CL2 and CL3 speaker 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.
Do I need CL2 or CL3 speaker wire?
CL2 cable must accept a maximum voltage of 150 volts, while CL3 handles up to 300 volts. Both are adequate for most speaker installations, and CL3 can be used in place of CL2, though CL2 cannot be used if CL3 is required.
What is CL3 speaker cable?
CL3: CL3 stands for “Class 3” wire and is also defined in Article 725 of the National Electric Code. Broadly speaking, it mirrors the definitions of Class 2 wire, but the jacket is designed to protect against voltage spikes of up to 300 volts.
What does CM CL2 mean?
Common Jacket Ratings
| Rating | Usage |
|---|---|
| CMP | All in-wall, plenum and riser applications. |
| CMR, CL3R, CL2R | All in-wall and riser applications; not permitted in plenums. |
| CM, CMG, CL2 | In-wall rated; permitted in 1-2 family residential riser applications, or in riser with raceway/fireproof shaft; not permitted in plenums. |
What is difference between Cl2 and CL3?
The key difference between Cl2 and Cl3 is that 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. Cl2 and Cl3 are chemical species containing chlorine atoms.
Why is chlorine always Cl2?
Chlorine is called Cl2 because it is a diatomic molecule. Diatomic means there are two atoms of the same elements in the molecule. There are other diatomic molecule, such as hydrogen (H2), nitrogen (N2), oxygen (O2), fluorine (F2), chlorine (Cl2), bromine (Br2), iodine (I2).
Is CL3 in-wall rated?
The high-speed cable quickly connects a wide range of HDMI devices and is CL3-rated for safe in-wall use and supports up to 300 volts.
Is CL3 in wall rated?
What does CL3 rating mean?
CL3. A CL3 rating is very similar to CL2 in the respects that they are both usable in wall, and are both resistant to holding and carrying flames. The main difference between the two is the wattage that a CL3 rated cable can carry.
What is CL3?
Cl3 is an anion of chlorine. We call it trichloride anion. It forms when a chloride anion (Cl–) reacts with a Cl2 molecule.
Is Cl2 a chlorine?
Why chlorine is written as Cl3?
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 is the difference between Cl2 speaker wires and CL3 speaker wires?
The only difference between them is CL3 speaker wires can take 300 volts, compared to 150 volts of CL2 speaker wires. Take this in mind when selecting your indoor/outdoor speakers.
Where can cl2r and cl3r cables be installed?
They can be installed anywhere except plenums. CL2R and CL3R are the riser versions of CL2 and CL3, meant to carry higher voltages. CMP: The “P” obviously stands for plenum, so this communications cable can be used in plenums in addition to anywhere that CM and CMR cable can be run.
What is the difference between riser cable and Cl2 cable?
Riser rated cable is used between floors. Imagine if you have a 3 story house; in between those floors is space for the wire to run through, this is where riser rated cables come in. If you have a multi-channel speaker set-up at your house, CL2 cables can help you connect multiple speakers on different floors.
What is the difference between Cl2 and cl2r?
Aside from being able to withstand 150 volts, CL2 cables are also classified as “Riser Rated” (CL2R) and “Plenum Rated” (CL2P). Riser rated cable is used between floors. Imagine if you have a 3 story house; in between those floors is space for the wire to run through, this is where riser rated cables come in.
