Wire nuts are small, plastic caps with a threaded screw inside. They look like small, cylindrical nuts, but they are designed specifically for connecting electrical wires.
Here's a more detailed description:
- Shape: Wire nuts are typically cylindrical or slightly conical.
- Material: They are made from a non-conductive plastic, often nylon or polycarbonate.
- Size: They come in various sizes to accommodate different wire gauges.
- Color: Wire nuts are usually colored to indicate the wire gauge they are compatible with. For example, red wire nuts are often used for 14-gauge wire, while yellow wire nuts are used for 12-gauge wire.
- Screw: The threaded screw inside the wire nut clamps the wires together, creating a secure electrical connection.
Here's an example of what a wire nut looks like:
Practical Insight:
When connecting wires with a wire nut, ensure that the wire ends are stripped to the correct length. The wire ends should be inserted into the wire nut until they reach the bottom, ensuring a secure connection.
