Hook Up Wire Data Chart

Hook up wire is commonly used for internal wiring of electrical equipment, control panels, appliances, and electronic assemblies. Because different types of hook up wire vary in insulation material, temperature rating, and voltage classification, selecting the correct construction is essential for compliance and performance.

This hook up wire data chart provides a side-by-side comparison of common types of hook up wire across multiple industry standards and designations, including UL, MIL-spec, automotive primary wire, and building wire constructions. It allows users to compare construction differences, voltage and temperature ratings, insulation materials, and conductor characteristics in a single consolidated reference.

Hook Up Wire Specifications by Standard and Construction Type

¹  Some hook-up wire types are available in stranded (STR) or solid (SLD) wire builds; see the Stranded vs. Solid Hook Up Wire Construction section for information on choosing a build. We have provided dimensions for the typical stranded constructions, but please note that variations in the stranding can affect this diameter.

²  These bare conductor dimensions are provided for reference only. The actual bare diameter can slightly vary depending on the conductor's material and the wire stranding. See a product page to determine the nominal value for that specific type of hook-up wire. 

All values are nominal unless otherwise specified.

The table above summarizes common hook up wire constructions and their key specifications across multiple industry standards.

This specification chart is designed to help users:

• Compare different hook up wire types
• Review insulation materials such as PVC or PTFE
• Confirm voltage and temperature ratings
• Identify compliance with applicable standards (UL, MIL, SAE, and building wire classifications)
• Evaluate construction differences across wire options

Whether selecting UL1007, UL1015, MIL-spec PVC or PTFE, THHN, GPT, SXL, GXL, TXL, or other constructions, this hook up wire data chart provides a structured reference for reviewing wire specifications.

Hook up wire is classified primarily by its insulation material and the applicable industry standard or designation, such as UL, MIL-spec, SAE automotive, or building wire classifications. Each construction carries specific performance ratings that define its intended use.

The hook up wire voltage rating defines the maximum operating voltage the insulation system can withstand, while temperature rating identifies the permitted conductor temperature under normal conditions. Insulation material (such as PVC or PTFE) and conductor stranding influence flexibility, durability, and environmental performance.

Reviewing these characteristics together allows users to compare hook up wire constructions and select the appropriate option for their specific application requirements.

Hook up wire is manufactured in either stranded or solid conductor constructions, and this distinction is reflected in the specification data shown in the chart above. A stranded conductor consists of multiple smaller strands bundled together to form the required gauge, while a solid conductor is a single piece of metal.

Stranded hook up wire is generally more flexible and better suited for applications involving movement or repeated bending. Solid wire offers greater rigidity and typically maintains its shape once formed. Conductor construction may also influence overall diameter and installation considerations. Both stranded and solid constructions are manufactured to meet applicable hook up wire standards and ratings.

While a general wire gauge chart focuses on conductor diameter and an ampacity chart identifies current-carrying capacity, this hook up wire data chart is centered on construction characteristics and applicable industry standards.

This page does not provide current capacity values. For current-carrying ratings, refer to the dedicated hook up wire ampacity chart. Instead, this resource supports evaluation of insulation type, standard designation (UL, MIL-spec, SAE automotive, or building wire), and performance ratings across multiple hook up wire constructions.

Hook up wire is used across a wide range of industries, where different environments may require specific insulation types, temperature ratings, or compliance standards.

For application-specific guidance, including ampacity and environment-based recommendations, refer to our dedicated automotive wire, marine wire, and electrical wire resources, which provide additional size charts and performance information tailored to their respective use cases.
