Application Scenarios

LED Lighting Projects Ideal for connecting the pigtail leads of LED strips to extension wires or directly to a low-voltage LED power supply. Perfect for creating custom-length connections in under-cabinet, cove, and accent lighting systems.
General Electrical and Automotive A must-have for any toolbox. Use for splicing wires in automotive audio systems, landscape lighting, security systems, and other low-voltage DC circuits where a reliable electrical splice connector is needed.
DIY Electronics and Hobbies Excellent for hobbyists and makers working on custom electronics, robotics, or model building. These connectors provide a secure, non-permanent alternative to soldering for prototyping and final assembly.

How to Use These Spiral Spring Wire Connectors

  1. IMPORTANT: Turn off all power at the source before beginning any electrical work.
  2. Carefully strip approximately 1/2 inch (12-13mm) of insulation from the ends of the wires you wish to connect.
  3. Align the stripped ends of the wires together, holding them parallel and even.
  4. Firmly push the aligned wire ends into the open end of the crimping cap.
  5. Twist the connector cap clockwise onto the wires until you feel firm resistance. The internal spring will grip and twist the wires together.
  6. Gently tug on each wire individually to ensure they are all held securely inside the connector.
⚠ Precautions
  • For safety and optimal performance, it is recommended not to reuse connectors.
  • Ensure the total number and gauge of wires used is within the capacity of the P2 connector.
  • These connectors are intended for use in dry, indoor locations only.
  • Always comply with local and national electrical codes for your application.

Frequently Asked Questions

Q: What does the P2 size designation mean?

A:P2 refers to a standard size for wire nut connectors, suitable for smaller gauge wires commonly found in lighting and electronics, specifically the 14-22 AWG range.

Q: Can I use these for both solid and stranded wire?

A:Yes, these spiral spring connectors are designed to work effectively with both solid and stranded copper wires, or a combination of the two.

Q: How many wires can I safely connect with one cap?

A:The number of wires depends on their gauge. For example, a P2 connector can typically hold two to three 18 AWG wires or up to four 22 AWG wires. Always ensure the connection is tight and secure.

Q: Do I need to pre-twist the wires before using the connector?

A:While not required as the internal spring is designed to twist the wires, pre-twisting them slightly can make it easier to insert them into the cap, especially when connecting multiple wires.

Q: Are these connectors waterproof?

A:No, these are standard connectors designed for use in dry, indoor environments. For outdoor or wet applications, you would need to use appropriate waterproof wire connectors.

Q: Can I use these for household AC wiring (120V/240V)?

A:These connectors are rated for up to 300V. While technically suitable for some AC applications, they are primarily used for low-voltage DC projects. Always consult and adhere to your local electrical codes for line voltage work.
