[RE-wrenches] DC circuit breakers in parallel

Hello Wrenches,

I am installing a Classic 150 controller in an RV with potential 95 amps output at 12 volts. The customer has a Midnite DIN box and wants me to use it for the controller output. 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.

Thank you,
