[RE-wrenches] DC circuit breakers in parallel

[Maverick Brown]

Larry

I hope you went ahead as planned. 

I have magnum 1500w inverter on my work truck. I paralleled 3 each of 60a breakers. I did not use parallel cables but installed a four finger MidNite bus bar on the bottom (allowing the addition of a 15A Charge Controller breaker) and a  3 finger bus bar on the top going to the inverter. 

I load tested and short tested the method. 

Thank you,

Maverick

I am out of 150VDC breakers but I have two 60 amp breakers. Is it safe and reliable to use the 2 breakers in parallel for this purpose? I can pin the two handles together. There will be other circuit protection at the battery.
