## Questions & Answers

**Q: It seems to be a polarized breaker, will it work properly to charge and discharge the batteries through it? I.e. current reverses during the charge.**
A: Wrong! there is a stamp in molding by poles which indicates which side is battery (batt) and Auxiliary aux. Battery side is on top in most cases.

**Q: 150A or 200A manual reset circuit breaker will be ok between battery bank and 3k inverter, using 2/0 wire?  Or should I fuse instead.?**
A: Remember 2/0 Copper Wire is rated up to 170 Amps. Installing a 200A breaker risks the chance of the wire overheating and causing a fire.

**Q: Would this 40amp be suitable for connecting my new 4000w generator to the main switchboard?**
A: No! This is a DC rated breaker if your generator makes AC power which I suspect it does you need a traditional AC breaker.

**Q: why there is more than 10% voltage drop in the Circuit Breaker ?**
A: If you're measuring 10% voltage drop across this breaker you have something wrong going on. High resistance within the Breaker.
