Type THHN or THWN-2 conductors are predominantly utilized in conduit as branch circuits within commercial or industrial applications, adhering to the specifications outlined by the National Electric Code. Type AWM or MTW conductors are primarily employed for appliance or machine tool wiring, as specified by the National Electric Code. These THHN or THWN-2 conductors are available in stranded forms for sizes 14 AWG to 750 kcmil, and in solid form for sizes 14-10 AWG. Stranded sizes from 14 AWG to 750 kcmil are also rated as AWM or MTW. The conductors, whether soft-annealed, stranded, or solid copper, are insulated with a resilient, heat, and moisture-resistant polyvinyl chloride (PVC). Additionally, a nylon (polyamide) jacket is applied. Sizes 14-750 MCM are equipped with a friction-reducing nylon jacket to facilitate the installation process.
