Application Scenarios
How to Use These Spiral Spring Wire Connectors
- IMPORTANT: Turn off all power at the source before beginning any electrical work.
- Carefully strip approximately 1/2 inch (12-13mm) of insulation from the ends of the wires you wish to connect.
- Align the stripped ends of the wires together, holding them parallel and even.
- Firmly push the aligned wire ends into the open end of the crimping cap.
- Twist the connector cap clockwise onto the wires until you feel firm resistance. The internal spring will grip and twist the wires together.
- Gently tug on each wire individually to ensure they are all held securely inside the connector.
- 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.
