I have two questions. First of all does anyone have any idea how to tell a good GFI breaker from a bad GFi breaker. Of course I wish to base the conclusion on the heat signature of said breaker.
Secondly in the quick insert charts a graph is included. If one generates a line across the line and load wires of a motor starter, one gets some very interesting graphs. Obviously the peaks is such a graph would represent the high temperature of the wires. Provided one had no reflections. My question is this would he troughs of such a graph represent the ambient temperature. I am attaching two photos o9ne of which uses isotherms. You will need to insert the second into a quick insert graph to see what I am talking about.
