<p>An electrical equipment cowling or cover (20) to be mounted on a channel section (1) can be of different height, e.g. 20, 30, 40 mm. The equipment has a base plate (10) with an inset cover (13) that encloses the open channel section to retain cables. The cover is marked with a series of break lines that allow the cover to be sized to suit the size of channel used. When a channel smaller than the available hole in the housing is used the remaining gap (30) can be enclosed with the aid of a special seal and this consists of two plate elements.</p> |
