   Hi All   
      
   I work with electric heaters and have a problem with moisture getting into the   
   element, causing the insulation resistance to drop.  The BS spec for immersion   
   heaters says it must be at least 2M ohm at 500V.  If I power up the heater it   
   can dry out and    
   recover.  Does anyone know the minimum insulation resistance that I need to   
   turn it on without causing permanent damage.  It seems to me that a leakage   
   current could cause "tracking" and make the component useless.
