Hi J
See we have the same problem. I am trying to build a test box for the light circuit. I too need to know what the breaking amp is for the thermal breaker inside the light switch. I have tried to look at several of them, but it does not state on them what the set point is.
Have looked at several different manufactures and no 2 are the same, but it seems to be a well kept secret.
Here is a photo - " exploded view" - of one that gave me grief " The key word here is "exploded" because that is exactly what it did. Seems there was too much juice to the front lights, but never can be sure, so I want to test the rest of the circuits.
Hope someone know the answer and will let us in on this well kept secret.
Chris.
