FPS Self-Regulating Heater
Technical Information

* Electrical equipment T-Rating codes define the maximum surface temperature that equipment will reach. It is used in hazardous (classified) area applications.

** For longer maximum circuit lengths under specific applications, consult SBA.

1. Circuit Breakers are sized per article 427-4 of N.E.C.
2. When using 240 volt product at 208, 220 or 277 volts, use the circuit adjustment factors shown in the voltage adjustment table.
3. When using 2 or more heater cables of different wattage ratings in parallel on a single circuit breaker, use the 15A column amperage of 15 amps, divide it by the maximum footage to arrive at an amps/foot figure for each cable. You can then calculate circuit breaker sizes for these combination loads. These amps/ft factors include the N.E.C. sizing factor in Article 427-4.
4. Heater cables with B, BA and BT optional constructions contain a metal ground shield. This qualifies them for use on non-metallic pipe (Article 427-23 NEC) and allows their use without ground fault protection (Article 427-22 NEC) for all applications except Division 1 hazardous areas.

General Note: Serge Baril strongly suggests that ground fault circuit breakers be used at all times in conjunction with the installation of heat tracers whether called for by the code or not.

Use of these products at other than rated voltages requires minor adjustments in power and maximum circuit lengths.
