Also, the soft starter is good for the motor. Note, a hard start capacitor is not a soft starter.
Don't worry about smaller motors, just your air conditioning. Inrush is typically 5 to 6 times running current. You will see it on the nameplate, LRA - locked rotor Amps. The soft starter limits the inrush current to 150% to 175% of running current. This lower starting current is good for your motor, breakers and wiring.
After one of the hurricanes, I sold an 8kW natural gas generator along with a soft starter for a 3 ton AC. Normally that generator would never be able to start that motor. With the soft starter, it fired right up.
