Hook-up wire is insulated wire commonly used for electrical connections. It can have a solid or stranded core made of materials like copper or aluminium and is covered with protective insulation, such as [PVC (polyvinyl chloride)](https://uk.rs-online.com/web/c/cables-wires/single-core-cable/hook-up-wire/?applied-dimensions=429487993) or [Teflon (PTFE)](https://uk.rs-online.com/web/c/cables-wires/single-core-cable/hook-up-wire/?applied-dimensions=4294851320). The insulation is colour-coded to indicate the wire's purpose and to help with identification in electrical circuits. To learn more about wiring colours, see our [Guide to UK Electrical Wiring Colours](https://uk.rs-online.com/web/content/discovery/ideas-and-advice/wiring-colours-guide ).

Hook-up wire is available in various gauges (wire diameters) and colours to facilitate easy organisation within electrical circuits. Heavier gauge wire, also known as equipment wire, has a thicker conductor and is designed to handle higher currents and voltages, making it ideal for powering large electrical equipment. The colour coding often follows industry standards or specific conventions, such as red for positive (+) connections and black for negative (-) connections in direct current (DC) circuits.

### **What are the types of hook-up wire?**

Here are some common types of hook-up wire:

1. **Single Conductor Wire:** This is the most basic type of hook-up wire, consisting of a single insulated conductor. It's suitable for general-purpose use and available in various gauges and insulation materials.
2. **Stranded Wire:** Stranded hook-up wire is made up of multiple smaller strands of wire twisted together. This construction makes it more flexible and suitable for applications where the wire may need to bend or flex.
3. **Solid Wire:** Solid hook-up wire consists of a single, solid conductor. It's less flexible than stranded wire but is preferred in situations where minimal signal loss or resistance is crucial, such as in high-frequency applications.
4. **Shielded Wire:** This type of wire has an additional layer of shielding, typically made of metal, around the insulated conductor. Shielded wire is used to protect against electromagnetic interference (EMI) and radio frequency interference (RFI). It's commonly used in audio and communication applications.
5. [**High-Temperature Wire**](https://uk.rs-online.com/web/c/cables-wires/single-core-cable/hook-up-wire/?applied-dimensions=4290886584 )**:** For applications where extreme heat resistance is required, high-temperature hook-up wire is used. These wires are designed to withstand temperatures significantly higher than standard wire.
6. **Multi-Conductor Cable:** While not technically a type of hook-up wire, multi-conductor cables consist of multiple insulated conductors bundled together within a single cable.
7. **Specialty Wire:** Some applications require speciality hook-up wire, such as magnet wire (enamel-coated wire used in electromagnets and transformers) or automotive-grade wire (designed for use in vehicles).
8. [**Harsh Environment Wire**](https://uk.rs-online.com/web/c/cables-wires/single-core-cable/hook-up-wire/?applied-dimensions=4290441716 )**:** refers to electrical wiring and cables designed specifically for use in extreme or challenging environmental conditions. These conditions can include exposure to high temperatures, moisture, chemicals, physical abrasion, and other harsh factors that standard wires may not withstand.
