Back to the basics... This is an electric heating element, it is known as a resistive load.  Ohms law can apply here very easily.  Let's say for instance we have an applied voltage of 208v to the element, using the resistance of the heater at 62.8 ohms we can insert that into ohms law to get a our pre determined amp reading.  208/62.8 = 3.31 amps.  #teachme
