There are two installation ways for the wires from the existing options for laying cable routes - internal and external wiring. Internal wiring implies that the cable lines are inside the walls. External wiring is installed on the walls from the outside. At the same time, it can be carried out either by wires or through protecting the cable from mechanical damage, for example, cable channels in which the conductor is located. The advantages of hidden wiring include more excellent reliability and durability due to the lack of the ability to cause damage in the normal mode of its operation. Such wiring requires less financial costs. And with the help of it, you can avoid eavestroughs.
