A 3HP saw only requires a 20 amp circuit and I believe a 5HP saw will be
fine on a 30 amp circuit.

Delta's catalog says 40 amp slow blow fuse for the 5 hp saw. I am not sure
what the equivalent circuit breaker would be, The starting current for a
single phase motor is quite a bit more than the rated amperes for the motor,
but of course that peak only lasts for a very short time.

They don't say what the circuit breaker or fuse size should be for a 3 hp
motor.

No matter what, the OP should consult an electrician for this kind of
question rather than the mighty mass of misinformation that is called the
internet.
