After installing a new motor you are experiencing what some call nuisance trips. Are they nuisance trips or is the motor trying to tell you something is really wrong? New doesn't always mean good. The first thing to do is look for a NEMA Code Letter on the nameplate. This letter will help you calculate the design locked rotor or In-Rush current the motor is supposed to see. Then use the MCEMAX® 6-channel In-Rush/Start-Up test to see the actual In-Rush current. If the actual current is not exceeding the design current, then you would want to focus your troubleshooting on the trip relay settings.
