What is the difference between cl2 and cl3 wire?

Rate this Question and Answer
Asked By: Cautar Talbi | Last Updated: 16th May, 2020
While CL2 and CL3 must pass the same tests for certification, the primary difference between the two cables is in the maximum voltage handling. CL2 cable must accept a maximum voltage of 150 volts, while CL3 handles up to 300 volts.





Similarly one may ask, is cl2 or cl3 better?

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. You don’t want the amplifier of a speaker to be stronger than a CL2/CL3 speaker wire or else it will blow out.

Similarly, what is the difference between cl2 and cl3 HDMI? 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.

Secondly, what is cl3 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.

What does CMR stand for in cable?
