I show how I wired up my solar battery box (including breakers, switches, and an inverter), what cables I used, and how I connected my polarized solar DC circuit breakers. You have to be careful how to wire up double pole DC breakers as they will cause fire if the polarity is wrong! I found the following videos how the cause fire but it was not really explained how you should connect them in a proper way. Thus, I created this video after I have done my research.

Videos of DC breakers causing fire:
   • Polarised Solar DC Circuit Breakers ...  
   • DC Circuit Breaker Fires
