UL 10485 wire selection
UL 10485 is a UL-certified PFA equipment wire rated 250°C and 600 V AC. This page covers small-gauge single-conductor constructions for internal appliance and electronic wiring, including separate solid and stranded 28 AWG options.
The dimension table runs from 30 AWG to 20 AWG with a nominal 0.20 mm PFA wall and a 0.15 mm minimum wall. Finished diameters, conductor construction and resistance at 20°C appear together so a buyer can check both electrical sizing and assembly fit. The conductor construction matters even where two catalogue rows show the same nominal finished diameter: a solid wire and a stranded wire require different handling and termination checks.
For a compact 600 V harness, start with the required conductor size and then review the available terminal opening and strip length. Include the conductor finish in the specification when the lead will operate close to 250°C. A temperature rating on the insulation cannot compensate for a terminal or adjacent component selected for a lower temperature.
See the Specifications tab for the model and size tables. Browse the high-temperature cable range for related constructions. Compare the larger-gauge UL 10503 and the PFA wire family.
Construction
UL 10485 uses the following conductor and insulation system. The diagram illustrates the layer sequence; select the conductor construction and covering shown in the required size specification.

| Component | Construction detail |
|---|---|
| Conductor | Copper; bare or plated construction selected for the temperature and termination |
| Insulation | Extruded PFA |
| Construction | Single insulated conductor |
Applications
UL 10485 is used for internal wiring of appliances or electronic equipment where the specified PFA construction, conductor size and temperature rating match the circuit.

UL 10485 replacement selection
For replacement enquiries, include the existing wire marking and the equipment connection drawing so the conductor, insulation and terminal arrangement can be matched.

Selecting the specified construction
State UL 10485, AWG and solid or stranded construction on the enquiry. Check the conductor finish, finished diameter and strip dimensions before substituting another PFA style.
For tight-clearance connections, use the agreed finished-diameter drawing: nominal conductor diameter and nominal wall values in the table do not always sum exactly to the listed outside diameter.
