The bars are secured by insulated supports. Three<br />
fixed supports, attached to the framework, are<br />
mandatory.<br />
If necessary, additional free supports may be used.<br />
The bars rest on a bottom support.<br />
The table opposite indicates:<br />
b the number and size of the bars to be used,<br />
depending on the permissible current level in the<br />
busbars<br />
b the number of supports required in a cubicle,<br />
depending on the rated short-time withstand current<br />
(Icw).<br />
The bars are secured by three mandatory fixed supports and<br />
two free supports.<br />
