What is Class 2 speaker wiring?

What is Class 2 speaker wiring?

Class 2 wiring refers to the National Electircal Code class for wiring, which indicates to the installer what type of wiring practice is needed, and to the inspector as an indicator of the specifications of the equipment without having to contact the manufacturer for every single item.

What is CL2 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.

What grade speaker wire should I use?

Thick wire (12 or 14 gauge) is recommended for long wire runs, high power applications, and low-impedance speakers (4 or 6 ohms). For relatively short runs (less than 50 feet) to 8 ohm speakers, 16 gauge wire will usually do just fine. It’s cost-effective and easy to work with.

Can I use 14 gauge wire for 8 ohm speakers?

The lower the gauge number, the thicker the wire. Thick wire (12 or 14 gauge) is recommended for long wire runs, high power applications, and low-impedance speakers (4 or 6 ohms). For relatively short runs (less than 50 feet) to 8 ohm speakers, 16 gauge wire will usually do just fine.

Is CL2 or CL3 better?

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.

Does speaker wire need CL2?

General Guidelines. For anything that is destined to go in-wall, you want unterminated CL2-rated cable. That includes your surround speakers, in-ceiling or in-wall speakers and anything that might run up inside a wall cavity—even for a short run. These are most common for interior wall-mounted televisions.

Can electrical copper wire be used for speakers?

Copper wire is the most commonly used type of speaker wire. It’s affordable and low in resistance. However, it’s prone to oxidation. Thus, it’s insulated to keep it protected from oxidation.

What is a Class 2 wire?

Class 2 wiring refers to the National Electircal Code class for wiring, which indicates to the installer what type of wiring practice is needed, and to the inspector as an indicator of the specifications of the equipment without having to contact the manufacturer for every single item.

What is the definition of a Class 2 circuit?

The NEC defines a Class 2 circuit as that portion of the wiring system between the load side of a Class 2 power source and the connected equipment. Due to its power limitations, a Class 2 circuit is considered safe from a fire initiation standpoint and provides acceptable protection from electrical shock.

What is a Class 2 voltage?

In general, a Class 2 circuit (operating at 24V with a power supply durably marked “Class 2” and not exceeding 100VA) is the type most commonly used. The NEC defines a Class 2 circuit as that portion of the wiring system between the load side of a Class 2 power source and the connected equipment.

What is a Class 2 cable?

CL-2 is an abbreviation for “Class 2” as it refers to the wiring code in the USA. Many states require low voltage cables to be “CL-2” rated in order for them to be installed inside the wall. A CL-2 rated cable has a slightly different outer insulation with a different fire rating.
