UL 758 AWM Style 1007 Lead Wire — 80°C / 300V PVC Insulated Hook-Up Wire
UL 758 AWM Style 1007 is a single-conductor PVC insulated lead wire recognised under UL’s Appliance Wiring Material (AWM) standard, specifically designed for internal wiring of appliances and electronic equipment. The designation “UL 758” refers to the UL standard governing AWM wire, while “Style 1007” defines the precise construction and performance requirements — including the 80°C temperature rating, 300V AC voltage rating, PVC insulation type, and horizontal flame performance.
Every reel of UL 1007 wire carries the UL Recognised Component Mark and is manufactured to the insulation thickness requirements verified by UL Solutions. The wire is available in solid or stranded conductor constructions across the full AWG range — making it one of the most versatile and widely specified AWM wires for appliance OEM wiring harnesses, control panel connections, and electronic device internal wiring worldwide.

What Is UL 758 AWM? — Standard Overview
UL 758 is the UL standard covering Appliance Wiring Material (AWM) — single and multi-conductor wires intended for internal wiring of appliances and electronic equipment. AWM wire is a UL Recognized Component, not a UL Listed product: it is certified for use inside finished appliances and equipment that carry their own UL product listing, rather than for installation in building wiring or conduit systems.
Under UL 758, wire styles are organized into five sections based on insulation material and construction type. Style 1007 falls in Section 1 — single-conductor thermoplastic insulation. Each style defines specific parameters: temperature rating, voltage rating, insulation material, minimum wall thickness, flame performance, AWG range, and permitted use description. When a finished appliance manufacturer specifies “UL 1007 wire” for internal wiring, they are referencing this complete parameter set — not just the insulation material.
UL 758 AWM Style Family — Complete Overview
Style 1007 is the entry point of the UL 758 AWM style family. Understanding the full style landscape helps procurement engineers select the correct wire when 1007’s 300V / 80°C specification is insufficient for a specific application:
| UL Style | Insulation | Temp | Voltage | AWG Range | Typical Use |
|---|---|---|---|---|---|
| 1007 | PVC | 80°C | 300V | 32–16 AWG | Appliance internal wiring, signal leads |
| 1015 | PVC | 80–105°C | 600V | 30 AWG–2000 kcmil | Motor leads, control panel wiring |
| 1332 | FEP | 200°C | 300V | 30–10 AWG | High temp appliance wiring, oven leads |
| 1569 | PVC | 80–105°C | 300V | 30–2 AWG | Thin wall, static appliance wiring |
| 1659 | PTFE | 250°C | 600V | 26–4/0 AWG | High temp internal wiring, motor leads |

Common Applications — UL 1007
Appliance Internal Wiring
UL 1007 is the most widely specified AWM wire for factory internal wiring of household and commercial appliances — washing machines, refrigerators, microwave ovens, air conditioners, and small kitchen appliances. The 300V rating covers standard mains-powered appliance circuits, and the horizontal flame rating satisfies the internal wiring requirements of UL appliance standards.
Electronic Equipment Wiring Harnesses
The fine AWG range (32 AWG to 20 AWG) makes UL 1007 the dominant choice for internal wiring harnesses in consumer electronics, computing equipment, telecommunications hardware, and industrial control electronics where multiple low-current signal and power circuits must be routed through compact enclosures.
Control Panel and Switchboard Wiring
Larger AWG variants (18 AWG to 16 AWG) are used for power distribution within electrical control panels, connecting MCBs, contactors, and terminal blocks where a UL-recognised wire with documented flame performance is required by the panel builder’s UL 508A listing.
Other Applications
- Medical device internal wiring (with appropriate derating)
- LED driver and lighting fixture internal connections
- Power supply and transformer internal lead wires
- Sensor and transducer connection leads
UL 1007 vs UL 1015 — Which to Specify

|---|---|---|
| Voltage Rating | 300 Vac | 600 Vac |
| Temperature Rating | 80°C | 80°C / 90°C / 105°C |
| AWG Range | 32–16 AWG | 30 AWG–2000 kcmil |
| Insulation Wall | 15 mils min avg | 30 mils min avg (30–9 AWG) |
| Typical Use | Low-voltage appliance and electronic internal wiring | Higher-voltage equipment, motor leads, panel wiring |
| When to Upgrade | If circuit voltage exceeds 300V → specify UL 1015 | If temperature exceeds 105°C → specify UL 3135 or 3266 |
Related UL Styles for Comparison
UL 1007 buyers commonly cross-reference: UL 1015 (80–105°C / 600V PVC, for circuits exceeding 300V or requiring higher temperature rating), UL 1569 (80–105°C / 300V PVC thin-wall, for static appliance wiring where compact diameter is a priority), UL 3266 (125°C / 300V XLPE, thermal upgrade at same voltage class with identical 15-mil wall form factor), and UL 3135 (200°C / 600V silicone rubber, for appliance wiring in high-temperature enclosures).
