- The heating cable shall consist of two 14 AWG nickel-plated copper bus wires, separated by a fluoropolymer spacer and helically wrapped with a self-regulating fluoropolymer fiber that controls power output so that the cable has an unconditional temperature identification number (T-rating) of T2C (446°F or 230°C) or lower without use of thermostats.
- A ground-fault protection device set at 30 mA, with a nominal 100-ms response time, shall be used to protect each circuit.
- The heating cable shall have a tinned copper braid with a resistance less than the heating cable bus wire resistance as determined in a type test (ASTM, B193, Sec. 5). The braid shall be protected from chemical attack and mechanical abuse by a fluoropolymer outer jacket.
- The heating cable shall have continuous exposure (maintain) capability up to 250°F (121°C) and intermittent exposure capability up to 482°F (250°C or 250 psi steam), as manufactured by nVent.
