@Keith k posted:Unfortunately I don’t have the knowledge to add to this very informative discussion, however when all is said and done it would be great to have a list of components and a diagram on how to incorporate these items. That would include breakers, diodes and tvs’s. Thanks to all the knowledgeable people for making this post possible.
Keith, that's a good suggestion. However, it might be difficult to come up with a one size fits all diagram, for all the possible breaker applications encountered in a model railroad layout. But there are some general points that could be addressed in your suggestion. Also, FWIW the diodes Pat mentioned are the TVS (Transient Voltage Suppression diode).
