If you’ve ever handled speaker wire or lamp wire, you might have come across zip cord—a flexible and easy-to-use type of electrical cable. But what is zip cord, and where is it used?
what is zip cord
In this article, we’ll explain the basics of zip cord, how it works, and why it's so common in low-voltage applications.
What Is Zip Cord?
Zip cord is a type of two-conductor electrical cable where the conductors are placed side by side in a flat, joined configuration and can easily be “zipped” apart by hand.
Each conductor is typically insulated in PVC or rubber, and the overall cable is very flexible and lightweight.
Key Features:
Two parallel insulated wires
Easy to split or separate by hand
Often polarity-marked (e.g. with a ridge or stripe)
Typically used in low-voltage or low-current circuits
Common Uses of Zip Cord
Zip cord is most commonly used in indoor, low-voltage wiring, such as:
🔈 Speaker Wire
Used to connect audio systems, home theater equipment, and PA speakers.
💡 Lamp and Small Appliance Wire
Found in table lamps, holiday lights, or extension leads for small appliances.
🔌 Low-Voltage DC Power
Used in 12V or 24V systems, such as for LED strips, hobby electronics, or battery-powered devices.
What Does Zip Cord Look Like?
Typically flat and flexible
Available in gauges like 18 AWG, 16 AWG, or 14 AWG
Comes in colors like clear, black, or brown to match household décor
One conductor is usually marked to indicate polarity (e.g., a white stripe or raised ridge)
Is Zip Cord Safe?
Yes—when used properly, zip cord is safe for low-voltage, indoor applications. But it should not be used for:
High-voltage or high-current circuits
Outdoor or wet locations (unless specially rated)
Permanent wiring in walls (not code-compliant for building installations)
Zip Cord vs Other Cables
| Feature | Zip Cord | THHN/Building Wire | Twisted Pair Cable |
|---|---|---|---|
| Type | Flat, parallel conductors | Single insulated conductor | Twisted insulated pairs |
| Voltage Rating | Low voltage (e.g., 300V max) | Often 600V | Varies (often data signals) |
| Flexibility | Very flexible | Less flexible | Flexible |
| Common Use | Lamps, speakers, DC power | Building wiring | Data, telecom, Ethernet |
Conclusion
What is zip cord? It’s a flexible, two-conductor cable ideal for low-voltage electrical uses like speakers, lamps, and LED lighting. Its ease of use, flexibility, and tool-free separation make it a favorite for DIYers, audio installers, and lighting professionals.
