Question

Difference between class 2 and class 5 copper cable

Answer 1

Class of conductor refers to the flexibility required for an application.

Class 2 is used in cases where the installation is fixed and they are stranded conductors. Class 5 refers to a flexible conductor.

The core of class 5 conductor has a number of thin wires than class 2 to make it more flexible.

Class 5 is better conductor comparison to Class  2 because conductivity is much more than of Class 2. 

When the load is increased then wire may get warmer and PVC of wire will be melted whereas, in Class 5 conductor it has more conductivity so it gets less warm than of Class 2.

Hope this will help you.
