Engineered for high-performance internal wiring, this 10 AWG UL 3173 hook-up wire is a heavy-duty solution for applications requiring superior thermal stability and moisture resistance. Featuring chemically cross-linked polyethylene (XLPE) insulation, this wire is designed to withstand the rigors of high-amperage industrial environments without melting or deforming.
UL 3173 is a premier choice for lead wire in motors, transformers, and switchgear. Its cross-linked insulation provides a significant advantage over standard PVC, offering better protection against chemicals, heat, and mechanical wear. The 10-gauge conductor is specifically suited for high-power distribution where low resistance and high durability are mandatory.
Advanced XLPE Insulation: The chemically cross-linked polyethylene insulation ensures the jacket remains stable at high temperatures and provides excellent dielectric strength.
High Thermal Rating: Rated for continuous operation at 125°C, making it suitable for Class B motor lead applications.
Tinned Copper Conductor: Features annealed tinned copper for superior solder-ability and maximum protection against corrosion and oxidation.
Exceptional Toughness: Provides high resistance to abrasion, crushing, and "cut-through" compared to standard thermoplastic insulations.
Chemical & Solvent Resistance: The XLPE jacket is highly resistant to common industrial oils, acids, alkalis, and solvents.
Standard Compliance: Meets UL Style 3173, UL Style 3195, and CSA Type CL1251 requirements.
Conductor Size: 10 AWG
Stranding: 105/30 (High Flexibility)
Voltage Rating: 600V
Temperature Rating: 125°C (257°F)
Insulation Material: Cross-linked Polyethylene (XLPE)
Insulation Thickness: 0.030 inches (0.762 mm)
Nominal Outer Diameter: 0.176 inches (4.47 mm)
Approvals: UL 3173, UL 3195, CSA CL1251
Motor Leads: Ideal for internal wiring of electric motors where heat dissipation is a factor.
Transformers and Switchgear: Used in power distribution equipment requiring 600V protection and high thermal resilience.
Appliances and HVAC: Suitable for heating and cooling equipment where wiring is exposed to elevated temperatures.
Control Panels: Frequently used in industrial control cabinets for power routing.
Technical Note: All dimensions and stranding counts are nominal and may vary slightly by manufacturer. This wire is designed for internal "hook-up" use and is not intended for use as a portable cord or in exposed structural wiring unless specified by local code.

UL 3173 is the safety standard for cross-linked polyethylene (XLPE) insulated wire. This rating confirms the cable is approved for 600V service and can operate continuously at temperatures up to 125°C (257°F), providing superior thermal stability compared to standard thermoplastic wires.
Standard extension cords use PVC, which is soft and rubbery. This wire uses XLPE, which is a "cross-linked" plastic. Think of it like the difference between a raw egg and a hard-boiled egg; once it's cooked (cross-linked), it won't melt back into a liquid. This toughness keeps the wire from getting crushed or cut inside heavy machinery.
125°C (257°F) is hotter than boiling water. Most wires are only rated for 60°C or 90°C. This high-temp rating means you can use a smaller wire to carry more power, or simply have a huge safety margin in "hot zones" like a motor housing or a large power supply where heat builds up quickly.
It is still high-quality copper, but it has been "Tinned." In industrial environments, copper can "rot" (oxidize) over time, especially where it gets hot. The tin coating acts like a suit of armor, keeping the copper fresh and making it much easier to get a perfect, permanent connection when you are crimping or soldering.
While it can handle the power, UL 3173 is technically an "Appliance Wire" (AWM). It is designed to live inside a machine or a panel. For a car, you'd usually want "SXL" or "GXL" wire which is specifically tested for engine bay vibrations and road salt, though UL 3173's XLPE insulation is actually very similar in durability.
Not quite! 10 AWG is typically used for heavy-duty individual circuits, like a water heater, a clothes dryer, or a large industrial motor. In a hook-up wire format like this, it’s usually the "main artery" inside a control box that feeds power to several smaller components.
This 10 AWG hook-up wire is a heavy-duty industrial conductor designed for the internal wiring of appliances, motors, and switchgear. Unlike standard house wire or automotive primary wire, UL 3173 features XLPE (Cross-Linked Polyethylene) insulation. This specialized material allows the wire to handle significantly higher temperatures (125°C) and resist melting or "flow" during soldering or high-current events, making it a staple in the manufacturing of transformers, control panels, and industrial heating equipment.
