That was a steal! sounds like a perfect complement to the battery bank.
Sure was RM! I already have an 800 amp to 50mV shunt and appropriate matching panel meter calibrated 0-800 amps DC.
I am also in the process of collecting bits and pieces to make a DIY EV (Electric Vehicle) because I thought it would be something
uber neat to play with.
Like I need more projects. I will need an identical type cct breaker for that project as well although I could get away with a 400 amp breaker.
I have four large, 3-phase, 100 amp, 600 volt AC Westinghouse breakers with a single paddle actuator that are seriously big physically from a 1954 RCA BTA10K AM broadcast transmitter installation. I would like to see if one of these with all 3 circuits parallelled might be good for say 300 Amps DC. If so, one of those could possibly work for my EV if the trip curve was generously slow. I plan to use one on AC as the master disconnect switch to my wind turbine alternator head. Since I already have these and they are really high quality breakers that can be used screwed to a plywood panel without a box if needed (very versatile), it will save me having to purchase expensive disconnect switches.
Doug was going to advise on the specs on my Westinghouse breakers for me but alas I have been lazy geting him the model number.
