Internal Built-in Components

US
US
Ascertaining the maximum number of conductors
US
Heat is generated in each terminal box. It is generated due to contact resistance at the
US
clamping units and due to the electrical lines installed in the enclosure.
However, the maximum permissible temperature of the terminal box must not be
US
exceeded! As a result, the current loads for the electrical circuits and therefore the
US
maximum permissible number of conductors must be observed.
US
5.3.1 Determine the Number of Conductors using the US EC Type Examination Certificate
US
The maximum permissible number of conductors can be read out of the table in the
US
US EC Type Examination Certificate for the type. Output data is the current load [in A]
and the conductor cross-section [in mm
US
To correctly use the specified number of conductors, please note:
US
Each inserted conductor and each internal connection conductor must be counted
US
individually.
US
Jumpers and protective conductors do not count.

In the white area of the electrical capacity table, the permitted numbers of the current carrying conductors inside the enclosure are indicated
(in and out counts as two wires) depending on wire size and continuous current.
In the shaded area of the electrical capacity table, additional conductors/terminals are permitted up to space limit of the enclosure.
In the area with dark diagonal lines, no conductors are permitted.
