Solid 14-10 AWG soft, uncoated copper per ASTM-B3.
Stranded 8 AWG conductor and larger uncoated per ASTM-B8.
Color-coded Polyvinyl Chloride (PVC) compound meeting the required thickness of Type THHN or THWN with a heat-stabilized Nylon rated for 90 C in dry or 75 C in wet locations.
Soft, uncoated copper per ASTM-B3 and or B8.
Maximum voltage rating for UF-B is 600 volts.
Type UF-B may be installed as interior wiring in wet, dry, or corrosive locations at temperatures not to exceed 90 C (with ampacity limited to that for 60 C conductors) as specified by the National Electrical Code.
Type UF-B may be used where exposed to direct rays of the sun or underground, including direct burial.
2 and 3-conductor constructions have the insulated conductors laid parallel. When a ground wire is present, it is laid in a valley between the insulated conductors.
A gray, sunlight-resistant PVC jacket is applied over the completed assembly.
