Rating	250 deg C, 600 Vac, Horizontal flame.

Conductor	18 AWG - 10 AWG, nickel-plated copper strands.

Insulation	Extruded MFA or extruded PFA, 20 mils minimum average, 18 mils minimum at any point.

Heating Element	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 contact with the copper conductor are dependent upon the wattage demand and the voltage used to energize the cable.

Assembly	Over two conductors laid parallel, extruded PFA or extruded MFA insulation 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 extruded insulation along the length of the cord so as to bare the copper conductor for approx 1/2 inches widths at periodic intervals.

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.

Covering	Optional. Fiberglass braid.

Jacket	Extruded MFA or extruded PFA, 20 mils min average, 16 mils minimum at any point.

Jacket	Extruded MFA or extruded PFA, 13 mils minimum at any point.

Shield	Optional.

Covering	Optional. Extruded MFA or extruded PFA, 13 mils min at any point.

Standard	Appliance Wiring Material UL 758.
