What is an important factor to consider when selecting cables for an installation?

When selecting cables for an installation, it is crucial to consider the cable's resistance to mechanical damage. Cables can be subjected to various environmental factors and physical stresses, such as impacts, abrasion, and exposure to chemicals, which can compromise their integrity and performance. Choosing cables that have appropriate mechanical protection minimizes the risk of damage that could lead to failures, electrical hazards, or even safety risks such as fire. This is particularly important in settings where cables may be exposed or where they are installed in areas with high foot traffic or industrial activity.

In contrast, factors like the insulation color or the aesthetic appearance may not significantly impact the cable's functionality or safety. While the length of the cable is a relevant consideration for ensuring adequate reach within the installation, it is not the primary concern when assessing the overall suitability and safety of the cable in relation to its environment. The focus should always be on the cable's operational capabilities and its ability to withstand the specific conditions in which it will be used.
