What is CL3 rated speaker wire?
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.
Do I need CL2 or CL3 speaker wire?
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.
Do I need CL3 speaker wire?
Wiring in-ceiling and in-wall speakers require using the right speaker cable. Both CL2 and CL3 speaker wires are ideal for running inside a wall or ceiling. Their only difference is that CL2 is safe for handling a voltage surge of up to 150 volts while CL3 can handle a voltage surge of up to 300 volts.
What is class 3 speaker wire?
Speaker wires used for this type of installation are rated as either Class 2 or Class 3. The only difference between classes is that Class 3 rated wiring is rated for a maximum of 300 volts and Class 2 has no such voltage rating.
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?
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 difference between CL2 and CL3 wire?
What is CL3 rated?
300 volts
In plain English that means that CL2 and CL3 are rating types for most types of low voltage cabling such as: speaker wire, Cat5/6, and HDMI cables. The difference between the two is that CL2 is rated for up to 150 volts while CL3 is rated for up to 300 volts.
What is CL3?
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. Furthermore, this anion does not exist as an individual chemical species.
Is CL3 better than CL2?
What are CL3 cables for?
They are both used for Video, Audio Interconnects, remote-control, signaling, and power-limited circuits. In plain English that means that CL2 and CL3 are rating types for most types of low voltage cabling such as: speaker wire, Cat5/6, and HDMI cables.
Is CL3 an element?
Cl2 and Cl3 are chemical species containing chlorine atoms. Chlorine is a chemical element having the symbol Cl and atomic number 17. It forms a wide range of compounds in combination with many other metals and nonmetals.
What is CL rated speaker wire?
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.
What is the best gauge speaker cable?
Lower gauge numbers are best to use, and most standard speaker wire is 16 gauge. Cables and Connections. Video equipment will need special cables and the cables, like speaker wiring, must be rated for the length needed.
What is wire classification Cl3?
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 725. They are both used for remote-control, signaling, and power-limited circuits. 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.
What is speaker wire for in wall wiring?
Lower-cost speaker wire is made of copper-covered aluminum , which also conducts electricity well, but aluminum is more prone to heat-related problems. Aside from use as a power cord, you might consider running speaker wire through your walls in low-voltage applications , such as thermostats, sensors and hard-wired smart-home devices.
