Series and Parallel configurations are made by moving the wire at the top of the 300-Watt 

resistor from the left position to the center position of the heavy-duty terminal block. 
 
Complete parts listings are given in the next five pages for the various Cathodic Protection 
Interface Systems available. The required system for various TEGs are listed below.
