I replaced my pump motor for a Jandy HHPU with a Centurion ST1102.  The original motor was 8/15 Amps.  The new motor is 7.2/14 Amps.  However, the breaker trip after 1 second of the motor starting.  I am certain I wired motor correctly, following the wiring insert in the package and the face plate.  White wire moved to L2 and brown wire moved to B for 115V.  Control panel wiring connected to the pump L1 and L2.  Also replaced the seals and o-rings for the pump.  

Any reason why my breaker keeps tripping?
