I normally don't go for cheap components. But for some reason I was soft in the head when I bought 2 cheap breakers off Amazon, a100 amp and a 50 amp. I have1020 watts of panels on the roof of my fifth wheel. While driving down the road in full sun the 100 amp Breaker that's between the SCC add main 12v bus would trip, I thought maybe ruff road might trip it so just never gave it another thought till this past week we were camped in full sun and once I was producing 55-60 amps after about 15-20 mins the breaker would trip. I just shut it off and went 4 days without charging. Which was fine because I have enough power and only went down to 60%. Well today I switched out the junk Breaker for a Bussman 100 amp I had. Pumping out 60_65 amps for about 3 hrs during peak time and Breaker was good the whole time. The only good thing about this is it might have never tripped if something shorted. Never seem to want to spend the many the first time but sure will the second time and will cost more.
