Re: 30a breaker for 40a spot on pdb
Bruce,
There was another team in Milwaukee that also tripped the main breaker. They thought is was protected as well but what we found was a small crack in the case. The slight misalignment was enough to cause the breaker to let go. There is another known issue with the breaker. A few over the years have shown up with manufacturing defect. A simple tap on the red button is sufficient to trip the breaker. The test is to tap with your finger and see if it fails. Over the last four years I think I have seen a total of less than ten.
