What is the purpose of training cable in installation?

The purpose of training cable in installation is fundamentally connected to avoiding tension. Training cable helps to properly guide the cable during installation to ensure that it is not subjected to excessive stress or strain. This is crucial because if cables are pulled too tightly, it can cause damage to the insulation, disrupt the circuit, or lead to premature failure of the cable over time.

Moreover, correctly trained cables facilitate a neat installation by allowing for appropriate bends and routing without pinching or kinking, which can also contribute to avoiding tension. Therefore, the method of training cable is significant in maintaining the longevity and performance of the electrical system being installed.

Other considerations, such as ensuring tight fittings or maintaining structural integrity, are secondary benefits that may arise from proper installation techniques but are not the primary focus of the training cable's purpose. Similarly, while allowing for easy repositioning can be a convenient feature, it does not capture the essential purpose of training cable.
