Why Are Push-in Terminal Blocks Not Suitable For All Wiring Scenarios?

In many practical cabling projects, push in type terminal block was once considered the preferred solution. However, it is not suitable for every wiring situation.

Some scenarios require higher physical stability and adaptability in the connection method, such as handling large cross-sections, multi-strand wires, or wiring environments with strong vibrations, high current loads, or long-term operation. Compared to tool-free, front-end insertion designs, traditional screw-type or spring-cage terminals are more advantageous in handling these "heavy load" conditions.

Other projects have strict regulations regarding wire type, wire diameter, insulation requirements, and long-term aging performance. Using push in terminal block wire connector may result in loose wires, poor contact, or even non-compliance with relevant standards and specifications. In such cases, screw clamps or traditional crimp terminals are more reliable.

Therefore, after a comprehensive assessment of wire type, operating environment, maintenance frequency, and load conditions at the beginning of the project, the decision to use push connector block should be made based on the actual situation. This choice better meets the project requirements and is more in line with professional wiring specifications and long-term operational stability requirements.
