5.1.2. Examples of positioning the connection busbars according to the types of terminals
The connection busbars enable the connection between the terminals of the circuit-breakers and the busbars of the switchgear.
Their sizing must be carefully studied by the switchgear designer. Some examples of possible constructions in relation to the
shape and size of the circuit-breaker terminals are given in this paragraph. The various types of terminals are of constant dimen-
sions for each size of circuit-breaker: it is normally advisable to exploit the whole contact surface of the terminal, so the width of
the connection busbars should be the same as that of the terminal. Different connection capacities can be obtained by adjusting
the thickness and number of busbars in parallel. In some cases, reductions in the width of the connection in relation to that of
the terminal are allowable as shown in the following examples.
