Technical Specifications

  1. The heating cable shall consist of two 16 AWG or larger nickel-plated copper bus wires, embedded in a self-regulating polymeric core that controls power output so that the cable has a temperature identification number (T-rating) of T4 (275°F or 135°C) without use of thermostats.
  2. A ground-fault protection device set at 30 mA, with a nominal 100-ms response time, shall be used to protect each circuit.
  3. 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.
  4. The self-regulating heating cable shall be specifically FM Approved or CSA Certified for use in Division 1 locations.
  5. The temperature identification number (T-rating) of the cable used shall comply with FM and CSA requirements as applicable.
  6. Connection methods used with the cable shall be compatible and approved as a part of the system manufactured and supplied by the heating cable vendor for use in the Division 1 location.
  7. The heating cable shall have continuous and intermittent exposure capability up to 225°F (110°C).
