Power cut out while running floor maintainer - breaker blown?
When you reset the breaker were you sure to first go to the off and than on position?
When a breaker trips it goes into the trip position which is centre on the handle. But to reset it, you need to go to move the handle to the off position and than the opposite way to the ON position. Sometimes people forget to go off first and just try to go from tripped to ON which will not work.
