<p>An enclosure for live electric material adapted such that at least one tunnel (23) intended for cable inlet is formed between a folded-in edge portion (17) of one of the side walls (11) of the enclosure and the mounting surface (22). The height and length of the tunnel have such dimensions that the requirements according to the standards regarding semi-protection are fulfilled. A rubber moulding (25) may be mounted in the tunnel (23) as protection against dust. A water-repellent design is provided by supplementing the enclosure with a separate rear panel (18), the upper edge portion (19) of which towards the tunnel is bent so as to form a labyrinth, thus obtaining protection against penetration of water. <IMAGE></p> |
