The manufacturer shall specify the type of conductor (hard or cord) to which the terminal can be connected, the cross-sectional area of ​​the minimum and maximum conductors, and the number of conductors connected to the terminal block at the same time. The maximum cross-section of the connecting wires allowed for the terminals shall be not less than the cross-sectional area of ​​the conductors specified in the temperature rise test.
The standard cross-section dimensions of copper conductors are as follows:
0.5,0.75,1,1.5,2.5,4,6,10,16,25,35,50,70,95,120,150,185,240,300mm2
Connection technology
The terminal block should be easily accessible and connected to the external conductor;
Terminals are usually used to clamp a single wire, but should also be considered suitable for clamping more than one wire;
The screws and nuts used to clamp the wires on the terminals should not be used as other parts.
