Well,........yeah. The National Electrical Code book
says a 7.5 Hp motor run on 120 volts will draw closer
to 80 amps, on 230 volts it will draw 40 amps, 240
will be slightly lower yet.
Use a time delay fuse or motor rated breaker with #8
wire, depending on how long the run is, if it's over
100 feet use #6, copper, of course.
Don't be afraid of conduit,
Joe
