UL 1056 Refrigerating Equipment Wire 16 AWG — 600 Vac, Stranded PVC, Indoor and Outdoor Rated
UL 1056 in 16 AWG delivers 600 Vac insulation in a stranded single conductor with extruded PVC wall rated at 105°C maximum, recognised for internal wiring of both indoor and outdoor refrigerating equipment. The stranded-only construction at 16 AWG provides the flexibility needed for wiring harnesses that must route around compressor fittings, fan motor brackets and cabinet framing in split-system and self-contained refrigerating units. 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 16 AWG suits fan motor leads, internal control circuit conductors and intermediate-gauge power wiring in residential and light-commercial refrigerating units, including split-system condensing units and self-contained display cases installed outdoors. The outdoor rating makes this size suitable for condensing unit control wiring that must meet the same UL component recognition as the indoor evaporator section. Where the wiring contacts refrigerant oil, specify the 60°C or 80°C oil-resistant option at time of order. For applications outside refrigerating equipment, confirm application suitability before specifying.
