UL 1056 Refrigeration Wire 14 AWG — 105°C Maximum, 600 Vac, Heavy-Wall PVC for Compressor Environments
UL 1056 in 14 AWG is a stranded single-conductor wire with extruded PVC insulation, rated 105°C maximum at 600 Vac, specifically recognised for internal wiring of indoor and outdoor refrigerating equipment. At 14 AWG, it suits the motor lead and power feed circuits inside hermetic and semi-hermetic compressor assemblies where sustained elevated temperatures and occasional refrigerant oil exposure make a 105°C-rated, oil-optional wire the correct component choice. CableApex supplies this size as a UL Recognized Component — file on record.

Applications
Within its permitted use — internal wiring of indoor or outdoor refrigerating equipment — UL 1056 14 AWG suits motor lead connections, compressor power feeds and internal control wiring in residential refrigerators, commercial display cases and outdoor condensing units where wiring passes through zones approaching or reaching 105°C and the circuit voltage is within 600 Vac. Where the wire also contacts refrigerant oil, specify the 60°C or 80°C oil option at time of order. For applications outside refrigerating equipment internal wiring, confirm application suitability before specifying.
