<p>In a metal cabinet accomodating electric control and switching apparatuses there are provided elements (1), which are made as a single piece of electrically insulating material, for supporting, by means of a first protruding portion (4), the electric cables that are associated to said apparatuses and that extend in a first direction (X-X), for instance inside a raceway (2A). The support elements (1) are conceived in a rational manner and are fastened, by means of snap-fitting means (6A, 6B), on to a wall of the cabinet; they preferably comprise also a second protruding portion (18) to support a second raceway (2B) containing electric cables that extend in a second direction (Y-Y) running perpendicularly with respect to said first direction (X-X). <IMAGE></p> |
