UL 1429

UL 1429 Wire Explained

UL-approved appliance and hookup wire UL 1429 uses irradiated cross-linked polyvinyl chloride (PVC) insulation. This process changes the properties of PVC from a thermoplastic that softens and burns when heated to a thermoset polymer that does not become soft or burn when heated. UL 1429 wire has a 150-volt rating and a maximum operating temperature of 80 °C. This wire also meets the requirements of the military specification MIL-W-16878/1.
