           Electric Usage 
            
            In electric usage the output is limited by the wattage of the element 
            which is sized according to the type of rail and may be approximately 
            75, 100, 150, 250, 300, 400 or 500 watts. 
  Most elements supplied encapsulate 
            an operating thermostat at 70 degrees Celsius or 5%.  An additional 
            thermal fuse cuts the element out in the unlikely event that the temperature 
            rises to 90 degrees Celsius. 
  In all cases the emission capability 
            of each rail is greater than the maximum output of the element. |
