UL 20846
Additional Details
APPLIANCE WIRING MATERIAL
Style 20846 Parallel cable with extruded insulation and jacket.
Rating 150, 200 deg C, 600 Vac, Horizontal flame.
Conductor 18 AWG – 12 AWG, stranded only.
Insulation FEP, 10 mils min average, 9 mils minimum at any point.
Assembly Over two FEP insulated conductors laid parallel, a 10 mil min avg, wall of FEP is extruded to form a two conductor parallel cord. This cord is now prepared for the spiral wound heating element. This is done by carefully removing the FEP insulation along the length of the cord so as to bare the copper conductor for approx 1/2 in widths at periodic intervals. A spirally wound nichrome or other types of resistance wire is then carefully wound the length of the core, and may be soldered to the exposed conductor. By varying the distance between contacts with the conductors, the number of turns per inch of resistance wire and the AWG size (resistance) of the spirally wound wire, different wattages per foot per service voltage can be obtained.
Shield Optional.
Covering Optional. 13 mils min at any point of extruded special copolymer of ethylene and tetrafluoroethylene (ETFE). See Facing Page for Compound Designation or FEP.
Jacket ETFE, 30 mils min average. See Facing Page for Compound Designation.
Standard Appliance Wiring Material UL 758.
Marking General.
