1. Introduction
When working with electrical wiring, it’s important to choose the right type of wire for safety and performance. Two common UL-certified wires are UL1015 and UL1007.
But what’s the difference between them?
- UL1015 is designed for higher voltage applications (600V) and has thicker insulation.
- UL1007 is a lower voltage wire (300V) with thinner insulation, making it more flexible.
Understanding these differences helps engineers, manufacturers, and buyers choose the right wire for their specific needs. Let’s dive deeper into their certifications, specifications, and best use cases.
2. Certification & Compliance
Both UL1015 and UL1007 are certified under UL 758, which is the standard for Appliance Wiring Material (AWM).
| Certification | UL1015 | UL1007 |
|---|---|---|
| UL Standard | UL 758 | UL 758 |
| CSA Compliance (Canada) | No | CSA FT1 (Fire Test Standard) |
| Flame Resistance | VW-1 (Vertical Wire Flame Test) | VW-1 |
Key Takeaways
✅ Both wires pass the VW-1 flame test, meaning they have good fire resistance.
✅ UL1007 is also CSA FT1 certified, making it more suitable for Canadian markets.
3. Specification Comparison
| Specification | UL1015 | UL1007 |
|---|---|---|
| Voltage Rating | 600V | 300V |
| Temperature Rating | -40°C to 105°C | -40°C to 80°C |
| Conductor Material | Stranded or solid tinned copper | Stranded or solid tinned copper |
| Insulation Material | PVC (Thicker insulation) | PVC (Thinner insulation) |
| Wire Gauge Range (AWG) | 10-30 AWG | 16-30 AWG |
Key Takeaways
✅ UL1015 can handle twice the voltage (600V vs. 300V), making it better for industrial power applications.
✅ UL1007 has thinner insulation, making it more flexible for small electronic devices.
✅ UL1015 can handle higher temperatures (105°C vs. 80°C).
4. Key Features & Differences
UL1015 – Heavy-Duty, Industrial Wire
✔ Higher voltage rating (600V) for power supply and industrial control panels.
✔ Thicker PVC insulation provides better protection from heat and damage.
✔ Used in HVAC systems, industrial machinery, and automotive applications.
UL1007 – Lightweight, Flexible Wire
✔ Lower voltage rating (300V), ideal for electronics and internal wiring.
✔ Thinner insulation, making it more flexible and easy to route through tight spaces.
✔ Used in LED lighting, circuit boards, and consumer electronics.
5. Application Scenarios
Where is UL1015 Used?
✅ Industrial Equipment – Used in power supplies, control panels, and HVAC systems.
✅ Automotive & Marine Wiring – Great for high-voltage automotive components.
✅ Heavy-Duty Applications – Suitable for factories and machinery where extra protection is needed.
Where is UL1007 Used?
✅ Electronics & Appliances – Ideal for internal wiring in TVs, computers, and small devices.
✅ LED Lighting Systems – Commonly used for low-voltage LED circuits.
✅ Consumer Electronics – Found in smartphones, chargers, and home gadgets.
6. Market Demand & Manufacturer Preferences
| Market Segment | UL1015 Preferred By | UL1007 Preferred By |
|---|---|---|
| Industrial Manufacturing | Siemens, ABB, Schneider Electric | Panasonic, Sony, Samsung |
| Power Distribution & Control Panels | Electrical panel manufacturers | Low-power industrial controls |
| Electronics & Consumer Goods | Limited use | PCB wiring, LED lighting |
Key Takeaways
✅ UL1015 is in demand for industrial manufacturers who need reliable high-voltage wiring.
✅ UL1007 is widely used by electronics companies for circuit board wiring and consumer devices.
7. Conclusion
