UL 1283 PVC Internal Wiring Wire 8 AWG — Entry Gauge of the Style, 105°C at 600 Vac with 60-mil Wall
UL 1283 in 8 AWG is a single-conductor internal wiring wire with extruded PVC insulation, rated 105°C maximum at 600 Vac, available in solid, stranded or braided conductor construction. As the finest gauge in the style’s 8–2 AWG range, 8 AWG is where UL 1283 begins — and where it picks up directly from the heavy end of UL 1056, which stops at 10 AWG. The two styles share an identical 60 mils minimum average PVC wall and the same 105°C / 600 Vac rating, so a design that needs conductors spanning both ranges can maintain consistent insulation characteristics across the full span. CableApex supplies UL 1283 8 AWG as a UL Recognized Component — file on record.

Conductor Choice at the Fine End of the Range
At 8 AWG, the three conductor constructions permitted under Style 1283 produce genuinely different handling characteristics. Solid 8 AWG is stiff and holds its shape once formed, which suits short fixed runs between a terminal block and a mounted component where the wire route will not change over the equipment’s service life. Stranded 8 AWG offers conventional flexibility and is the general-purpose choice for routed internal wiring. Braided 8 AWG — built from 40–20 AWG fine strands — is markedly more supple than either alternative and is worth specifying where the conductor must be dressed around structural members, where the equipment design requires the wire to be disconnected and refitted during servicing, or where the installation transmits vibration to the conductor. All three carry identical UL recognition, insulation wall and ratings, so the selection is purely a handling and installation decision.
Applications
Within its permitted use — internal wiring, with the optional 2500 V peak electronic use tag — UL 1283 8 AWG suits internal power feeds, sub-panel distribution conductors and bus connections inside equipment enclosures operating at up to 600 Vac with ambient temperatures reaching 105°C. Where the tag marking 2500 V peak — for electronic use only is required for internal electronic circuits, specify it at time of order. Where the wiring contacts oil inside the equipment, the optional 60°C or 80°C oil-resistant rating applies. Equipment-type-specific installations such as machine tools or control cabinets fall outside the explicit permitted use description; confirm application suitability before specifying for those end uses.
