tips needed to chase dc short
Lots of great ideas here - I'm working through them and will spend some quality time chasing it this weekend. Some clarification : In my panel the tripping breaker is connected to a bus bar with a total of six other breakers. None of the others have any issues. The breaker in question powers the starboard (don't know why I said port before) side cabin lights and two small fans. The lights and fans work when the breaker is first turned on and then it flips off. Even with all lights and fans switched off, the breaker will still flip. On the panel there is a cumulative analog ammeter that shows the total load across all breakers. This appears to be working properly as I can watch the load build as I turn circuits on, and the bigger items like the icebox show a bigger load etc. for regular usage it stays between 5 and 10 amps. However, as soon as I turn on the starboard breaker switch the meter goes above 20 and stays there until the breaker flips off.
