The amps draw per leg was around 235 each. a=235amps, b=235amps, c=235amps

Thanks for the clarification.

Our Generator was installed a few weeks ago and it has a slick microprocessor display, with the Total amps reading.

This 700 amp breaker has a little switch assembly Called a "ground-censor" on the panel below the breaker that could be sensing a fault somewhere.

I'll post more details soon.
