¹ Some hook-up wire types are available in stranded (STR) or solid (SLD) wire builds; see the Stranded Wire or Solid Wire? section below 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.

Stranded Wire or Solid Wire?

Hook-Up Wire is often available in two constructions – stranded and solid. The conductor of a stranded wire consists of multiple strands of smaller-sized wire that are bundled together to create an equivalent to a larger-sized wire. A solid wire’s conductor is simply a single piece of larger-sized wire.

Typically, stranded wire is more flexible and can withstand repeated bends better than solid wire can. This makes stranded wire ideal for being used in a busy environment where it could often be bent or otherwise moved. On the other hand, solid wire is usually very rigid, especially as you increase the wire size. This allows for a durable wire that will readily hold a shape if needed. Additionally, the conductor diameter of a solid wire tends to be smaller than that of a stranded wire (and thus, the overall diameter is smaller as well). As such, applications where the hook-up wire’s diameter is critical or where a certain form is desired are perfect for solid wire.

However, any given wire construction is designed to meet a hook-up wire’s standards and ratings. Therefore, stranded wire and solid wire will both deliver the performance you need to complete your project.

All values are nominal unless otherwise specified.
