⚡ Neutral & Grounding Connection
This terminal block is designed to provide a common connection point for compatible conductors.
The internal brass/copper strip electrically links the terminal positions, allowing multiple wires to be connected to the same conductive path where the electrical design requires it.
This can be useful for organizing:
- Neutral conductors
- Protective-earth conductors
- Grounding connections
- Common electrical connections
- Distribution wiring
Important: Neutral and protective-earth conductors are not interchangeable simply because both may use a common terminal block style. Their connection arrangement depends on the electrical system and applicable wiring regulations.
🔩 Brass / Copper Conductive Strip
The internal brass/copper strip serves as the primary conductive bridge between the terminal positions.
A dedicated conductive strip helps create a cleaner and more structured installation compared with joining several wires through improvised connections.
For reliable electrical performance, every conductor should be properly inserted into its terminal and securely clamped by the screw.
Always ensure that the conductor size and total electrical load are suitable for the selected terminal block.
🟢 Color Options for Wiring Organization
The product is available in blue, white, and green versions.
Color selection can help users visually organize different terminal assemblies inside an electrical enclosure. However, the housing color should not be used as the sole basis for identifying a conductor function.
Always follow the wiring diagram, conductor markings, local electrical codes, and the actual circuit design.
🧰 Multiple Pole Configurations
Choose the appropriate terminal size according to the number of wires required:
- 4 Pole – Compact option for smaller installations
- 5 Pole – Suitable for additional connection requirements
- 6 Pole – Practical for medium-size wiring arrangements
- 7 Pole – Provides extra connection capacity
- 8 Pole – Suitable for larger compatible installations
- 9 Pole – Additional connection points for more extensive wiring
- 10 Pole – Convenient for multiple conductor connections
- 11 Pole – Higher connection capacity
- 12 Pole – Suitable for installations requiring multiple common connections
Always verify the exact pole count, dimensions, wire capacity, and electrical rating of the selected version before ordering.

🔌 Installation & Wiring Tips
For a secure and reliable installation:
- Use wires compatible with the terminal's specifications.
- Confirm the appropriate conductor size before installation.
- Strip conductors cleanly without damaging the wire strands.
- Insert each conductor fully into the terminal.
- Tighten each screw securely.
- Keep bare conductor exposure to a minimum.
- Prevent loose wire strands from touching adjacent terminals.
- Verify the conductive bridge configuration before connecting circuits.
- Install the terminal inside an appropriate electrical enclosure where required.
- Label or identify the connected conductors according to the actual electrical system.
For mains-voltage installations, wiring should be performed by a qualified electrician or appropriately trained professional.
⚠️ Important Safety Information
- Always turn off and isolate electrical power before installation or maintenance.
- Do not exceed the actual voltage, current, conductor-size, or temperature rating of the selected terminal block.
- The product should only be used for the electrical function for which the selected configuration is designed.
- Do not assume a blue, white, or green housing automatically defines the conductor function.
- Do not connect neutral and protective-earth conductors together unless the electrical system specifically requires and permits that connection.
- This terminal block does not replace circuit breakers, fuses, RCD/GFCI protection, surge protection, grounding electrodes, or other required protective equipment.
- Ensure the grounding system is properly designed and connected.
- Do not use a grounding terminal as a general-purpose live distribution terminal unless specifically rated for that application.
- Protect the terminal assembly from moisture, mechanical damage, and accidental contact using a suitable enclosure.
- Follow applicable local electrical codes and safety requirements.
- For mains or safety-critical wiring, consult a qualified electrician.
