I should have known better.
When fitting my new lithium setup a few months past I realised, at the last minute, I hadn't ordered a circuit breaker so hopped onto eBay and bought an 80 amp job:
Circuit breaker
I wired the new system and all was good... at first.
After one week or so of occasional microwave oven use (50A) the 80A circuit breaker began to false trip, this became worse and it also began to go partially open circuit as thought its contacts were burned - in short it's a piece of crap and it had failed - after a couple of weeks!
I have replaced it with a Schneider 63A breaker which is mainly used in industrial AC applications but is also specified for DC up to, iirc, 56V, this is a professional piece of kit and costs $3 more (at $17) than the eBay crap.
My eBay CB is simply another example of a Chinese company not giving a stuff what they sell or the safety risks they create as long as they can make money from it. This is a cultural issue far more than a product quality issue.
