TPC 300 or TPC 400, what are the differences

ChooChoo1972OGR Forum Member

Hi, all I am in the wiring phase of my top level. I will section it off into two power districts. I plan on using one PH180 for a each district. I will connect the outer (common) rails. I would like to use a TPC between the PH and the track. I know there are two models, the 300 and 400. Can anyone tell me what the differences are? Any opinions and expertise and greatly appreciated as always.
