I was wondering if anyone could describe how a breaker test panel operates. I know you connect your breaker to the panel and you simulate that the breaker opens and closes through push buttons. But does anyone have more details.
What are the pros and cons of using water verses air for a hydro-static pressure vessel test? I have read places where they say that using water is better because it is virtually in-compressible but using air is dangerous because it is compressible? I guess there is something in ASME B31.1.
