You'll likely see labels like THHN or THWN written on the wire. For example, THHN wire stands for thermoplastic high heat-resistant nylon coated wire. THWN stands for thermoplastic heat- and moisture-resistant nylon coated wire. As you can see, these wires are built to take on many different conditions.
Voltage rating for cable is 600V. Conductors: THHN / THWN-2 / T90 conductor is a compact soft drawn bare 8000 series aluminum, with Class B stranding. Insulation: THHN / THWN-2 / T90 is low coefficient of friction (âslickâ), abrasion, heat, sunlight, and moisture resistant polyvinyl. chloride PVC. Jacket: THHN / THWN-2 / T90 cables have a clear abrasion, heat, sunlight, moisture resistant and low coefficient of friction nylon.
