Re: 30a breaker for 40a spot on pdb

There was a team at the Los Angeles regional who's circuit breaker would trip when they had a hard impact. After repositioning it and shock mounting it, it still occurred. They were able to reproduce the problem on the practice field by running it into the wall or over a bump hard. They replaced it with a new breaker and it didn't happen again.

What was the position of the black lever on the circuit breaker when you lost power?
