HVAC compressor circuit breaker trips. Change breaker from 30 to 35 amps safe?

What I've read about hard starts is you have more available current to turn the compressor over from a dead stop, allegedly, over time, will burn the compressor windings out. Mine with the 5-2-1 hard start sure fires faster and easier "audibly", at my house.

I suspect you are mistake about the hard start system increasing the starting current from the mains.

I suspect that you read increased starting torque, and presumed higher current. As I read it, the hard start kit adds a capacitor into the circuit during starting to increase the phase shift and therefore the torque.

What I know is that 3-wire pump with a start capacitor is easier on a generator during starting (requires less V-As) than classic 2-wire pump.

My suspicions could be wrong. Can you find anybody who says the hard start kit causes an increase in starting amps?

Update on my prior posts on this thread:
The new 35 amp breaker tripped again back in early June. Compressor would not start after resetting. Heard some unusual noises coming from outside earlier. HVAC contractor came out promptly the next day to diagnose. The compressor was seized up. Perfect timing, heat wave had just started that lasted a few weeks. Took about 2 weeks to get a replacement. New compressor installed under warranty. I had them install a soft-start kit while they were at it. It's been fine all summer now.

Let's start over.

Need to ask why the 30 amp breaker is tripping? Find out why?

On this my guess is corroded wire connections, dirty corroded lugs in the disconnect and on the contactor. All of this corrosion increases the impedance on the lines. High impedance causes more amp draw. More amp draw pops breakers sooner than normal.

I pulled all my wiring off. Polished up some terminals and cut off cables to allow fresh copper connections. If you have two fuses in your disconnect, break out the metal polish or some Flitz. Those turn over-able disconnects that have copper lugs, polish them like a new penny. Clean up ALL of the grounds while you are there.

I would check for a loose neutral in the panel. Make sure all the main legs are torqued down proper.

Great time to install a soft start kit on the outdoor unit.

Breaker tripping only occurred with the bad compressor, and the new compressor did not trip the breaker.
