    The breaker is intended to protect the wire which for 70amp would be #6. You can connect (2) loads to one breaker, as long as each of the loads is protected at their rating, usually done through a disconnect switch with fuses. Additionally the breaker should not be loaded more than 80% for a continious load (more than 3 hours) and for a motor load, should be sized 125% of the FLA.

    Are you asking how this should be done? Or are you asking if it is OK?

    This would only be true for THHN conductors in conduit. #6NM cable is only good to 60A
