Circuit Breakers

[Alumanutz]

I have started sorting out my electrical system on my 1966 Safari. When I opened up the junction box in the front I found a circuit breaker riveted to the cover. Is this stock? I know there are three breakers in the back for inside. Is there a way to test these breakers or should they just be replaced? On the internet they are only a few bucks. I would just need to figure out the amperage rating. Any thoughts?

The current rating of a circuit breaker is usually stamped in the top of the switch handle itself. If not there when you remove the breaker the part number and rating should be on the side.

As for a breaker riveted to the cover of the panel that sounds like an after thought.

If you want to test a breaker just apply a load that is at least 90% of the rating. Breakers are designed to trip at 80% of rating. A toaster and a hair dryer is a crude way but should trip a 20 amp breaker.
