Heat Tracing Questions

1. Why the heat tracing cables draw more current during starting at start up temperature?

2. How self regulated tracing cables are inherently safe and can be used in hazardous area?

3. How the Maximum circuit length is determined according to the breaker type? What is the equation used here? (see the picture below)

    EEEEErrrrrmmmmn.


    1. Cold = Lower electrical resistance. Hotter = higher resistance. Ohms Law.


    2, Dunno. What do you mean by a hazardous area. Car filling station? Gas works?


    3. Aren't they rated at so many Watts per meter?
