APPLIANCE WIRING MATERIAL
Subj.758 Section 2 Page 2712 Issued:1974-11-04
Revised:2012-04-26
Style 2712 Heating Cable.

Rating200 deg C, 600 Vac, Horizontal flame.
Conductor18-12 AWG, stranded only.
InsulationExtruded FEP, 10 mils min average, 9 mils minimum at any point.
Heating ElementNichrome, copper alloy or other suitable resistance wire is spirally wound around the insulation; the AWG size of wire, number of turns, length between contract with the copper conductor are dependent upon the wattage demand and the voltage used to energize the cable.
AssemblyOver two or three FEP insulated conductors laid parallel a 5 mil minimum at any point wall of FEP is extruded to form a 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 outer conductors so as to bare the copper conductor for approx 1/2 in widths at periodic intervals. A spirally wound nichrome or the type 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 resistnce wire and the AWG size (resistance) of the spirally wound wire, different wattages per foot per service voltage can be obtained. Heating Element - Nichrome, copper alloy or other suitable resistance wire is spirally wound around the insulation; the AWG size of wire, number of turns, length between contract with the copper conductor are dependent upon the wattage demand and the voltage used to energize the cable.
