7.5 hp compressor kicks breaker 50% of the time

80 gal 7.5 hp single ph changed the unloader valve and the pressure switch and had the motor sent out still acts the same.


Its almost that it builds pressure before the motor reaches speed and it struggles and then trips.

It has done this since new.

Even rewired to the breaker and changed the breaker same problem.

Then we need some basics.
What's the FLA of the motor?
What CB are you using?
wire size / length?
model number?
