How To Install Neutral Blocks Correctly? These Key Points Should Be Kept In Mind

As a key component of electrical connections, the correct installation of neutral blocks is crucial for the stability and safety of the circuit. The following points must be kept in mind.

Selection and adaptation: Based on the specifications and materials of the wires, as well as the current, voltage, and other parameters of the circuit, accurately select the appropriate type of terminal block. For example, high current circuits require the use of terminals with high current carrying capacity to avoid safety hazards caused by overload heating; When connecting wires of different materials, suitable terminals should be selected to prevent electrochemical corrosion.

Preparation: Before installation, carefully inspect the neutral blocks for any damages, cracks, or other defects to ensure their quality is qualified. At the same time, use appropriate tools to strip the insulation layer at the end of the wire to an appropriate length, generally to be able to fully insert into the terminal without being exposed, and avoid damaging the wire core during stripping.

Standardized installation: Insert the processed wires into the terminal holes to ensure proper insertion. For screw crimping terminals, a suitable screwdriver should be used to tighten the screw clockwise with moderate force, ensuring good contact between the wire and the terminal, and avoiding excessive tightening that may damage or break the wire; For plug-in terminals, they should be inserted vertically and smoothly. If you hear a "click" sound, it means they are reliably connected. Do not forcefully insert or diagonally insert them.

Check and confirm: After installation, carefully check whether the terminal connections are firm, and gently pull the wires to confirm that there is no looseness. Use a multimeter and other tools to check the continuity and resistance of the circuit, ensuring that the connection is normal and there are no faults such as short circuits or open circuits.

In addition, attention should be paid to the installation environment, and neutral blocks should be avoided from being installed in damp, high-temperature, and corrosive gas environments to avoid affecting their performance and service life.
