All,
Back to troubleshooting our electric floor heat.  Found the Paktronic unit.....its the actual Nuheat thermostat unit.  So my problem is this, the floor heat breaker will trip when I turn either thermostat up to command floor heat.  The breaker will stay set as long as I don't ask for any heat on either unit.  Several questions come to mind here;

• Is the master bath floor heat loop connected to the kitchen floor heat loop in some way?
  
• Is there a place to disconnect and ohm out the floor heat loops?
  
• In the master bath, is the engine trap door heated with the floor heat system?
  
• If so, where would the connection be?
  
• Is there a way to test the Paktronic unit?
  
• Is it possible that both Paktronic units are in need or rebuilding?
  

Thank you all in advance for the help.
