UL1007 vs UL1015 vs UL1028 vs UL1032: PVC Hook-Up Wire Guide
Choosing between UL1007, UL1015, UL1028 and UL1032 usually comes down to four variables: voltage rating, temperature rating, conductor size and the exact construction listed by the manufacturer. All four are UL 758 AWM hook-up wire styles, but they are not interchangeable across every application.
This guide compares the published data and explains how to narrow the choice before requesting a quotation. For a shorter comparison of the two most common styles, see the existing UL1007 vs UL1015 hook-up wire guide.
UL1007, UL1015, UL1028 and UL1032 at a glance
| Style | Voltage | Temperature | Insulation | Published AWG range | Typical selection driver |
|---|---|---|---|---|---|
| UL1007 | 300 V | 80 °C | PVC | 32-16 AWG | General internal wiring where a lower temperature rating is sufficient. |
| UL1015 | 600 V | 105 °C | PVC | 30-2 AWG | Higher voltage and higher temperature, including larger power conductors. |
| UL1028 | 600 V | 105 °C | PVC | 22-6 AWG | Applications that need a specific documented construction within the listed range. |
| UL1032 | 1000 V | 90 °C | PVC | 30-10 AWG | Higher voltage internal wiring where the temperature requirement stays within 90 °C. |
Voltage and temperature are not the only variables. Insulation wall, overall diameter, conductor construction and resistance also change by AWG. Open each product page and compare the full construction table before selecting a style.
UL1007: 300 V, 80 °C PVC hook-up wire
UL1007 is a common choice for internal appliance, control-panel and electronic-equipment wiring. The published construction table lists 32-16 AWG, with solid and stranded conductors, insulation walls around 0.39-0.46 mm and a 2000 VAC routine withstand test on every listed row.
Choose UL1007 when the working voltage stays within 300 V and the maximum conductor temperature stays within 80 °C. If either limit is exceeded, move to a higher-rated style rather than relying on the insulation thickness alone.
UL1015: 600 V, 105 °C PVC hook-up wire
UL1015 extends the range to 600 V and 105 °C and is available from 30 AWG up to 2 AWG in the published table. The larger sizes make it suitable for power and control wiring where a PVC hook-up wire is acceptable.
Because the AWG range is broad, two UL1015 constructions can be very different in diameter, flexibility and resistance. Compare the conductor construction and maximum resistance for the exact size you need.
UL1028: 600 V, 105 °C with a different documented construction
UL1028 shares the 600 V and 105 °C ratings with UL1015, but the published table covers 22-6 AWG and should be checked against the specific drawing or construction requirement. Do not treat UL1015 and UL1028 as direct substitutes without confirming the conductor construction, diameter and approval scope.
UL1032: 1000 V, 90 °C PVC hook-up wire
UL1032 is the higher-voltage option in this group. The published table lists 30-10 AWG and insulation walls around 0.80 mm in the listed rows. It is useful for internal wiring where the voltage requirement is higher but the temperature requirement remains within 90 °C.
When both voltage and temperature are high, compare UL1032 with an XLPE or fluoropolymer construction. Review the XLPE and high-temperature hook-up wire family and the fluoropolymer wire family before deciding.
How to choose the right style
- Start with the working voltage and the required temperature rating.
- Confirm the required AWG, conductor construction and maximum resistance.
- Check insulation wall and overall diameter against the connector, terminal and routing space.
- Review flexibility, abrasion, oil, chemical and moisture exposure.
- Confirm the applicable UL file scope and the exact construction on the product page.
- Send the BOM or drawing when the cable forms part of a finished assembly.
All four styles are part of the UL PVC and SR-PVC hook-up wire family. The family page links the available styles and the related construction tables.
Documentation and approval scope
The manufacturer catalogue cites UL File No. E170689 for the listed UL 758 AWM styles. Certification files are held by the manufacturer. Before relying on a style for a finished-product approval, request the issued document and confirm that the exact style and construction are within its scope. See the certification and approvals page for the available records.
FAQ
Is UL1015 always a replacement for UL1007?
No. UL1015 has higher voltage and temperature ratings, but diameter, flexibility, conductor construction and approval scope can differ. Confirm the full construction and the end-product requirements.
Can UL1032 replace UL1015?
Only after checking both voltage and temperature. UL1032 offers a higher voltage rating in the published data, but its temperature rating is lower than UL1015 and the AWG ranges differ.
What should I send for a quotation?
Send the style, AWG, conductor construction, colour, length and destination. If the wire is part of an assembly, include the BOM or drawing through the request a quote form.
