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 dimensions 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.
