The bars are secured by insulated supports. Three<br />
fixed supports, attached to the framework, are<br />
mandatory. If necessary, additional free supports may<br />
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 />
Above 1600 A, the busbars must be doubled and<br />
installed in two busbar sections, side by side. In this<br />
case, they must be interconnected by three<br />
equipotential links.<br />
The bars are secured by three mandatory fixed supports and<br />
two free supports.<br />
Busbars up to 3200 A.<br />

Busbar supports : directly fixed on frame (300 mm width duct)<br />
Three fixed supports are required to maintain the busbars. If more than 3 supports<br />
are required, use additional free supports.<br />
