Hello! I recommend reading this article, everything is written in it https://electro.tomathouse.com/en/kak-provesti-kabel-po-fasadu-zdaniya.html In short, the cable for outdoor installation should be armored or designed for outdoor wiring. In addition, the cable must be additionally protected from mechanical damage by laying in a special box. If there is no chance of damage, just put the cable in the corrugation. You should also understand that all connections and connections must be protected from moisture and dust.
