Capacity of electric cables, how to recognize them

7359 Views
Posted on: 2022-12-15
 

What is the capacity of an electric cable?

A wire's current capacity (or short circuit current) is the maximum amount of current that can pass through a wire before a short occurs. It is a fundamental measure of the safety of the electrical system.

How to identify the capacity of an electric cable?

To determine the capacity of an electric cable, you must first of all know the diameter of the cable and the number of conductors that make up the cable. The diameter of the cable can be measured with a gauge or with a wire mesh. The number of conductors is indicated on the cable label.

Electric cables: what are the tables for the correct capacity?

Once the characteristics of the cable have been measured, a capacity table can be used to identify the maximum capacity of the cable. Capacity tables vary according to cable type. For example, a H07RN-F type cable has a maximum capacity of 16A, while a H05VV-F type cable has a maximum capacity of 24A.

How to calculate the cable capacity?

Once the characteristics of the cable and the capacity table are known, it is possible to calculate the capacity of the cable. To do this, multiply the maximum capacity by the number of conductors. For example, if a H05VV-F cable has a maximum rating of 24A and contains three conductors, the rating of the cable will be 24 x 3 = 72A.
