I have Danaher Motion SS451 (120V, 60 Hz, Single Phase, 72 RM, page 10 in manual below) synchronous motor that was consistently blowing a 3 amp fuse. I replaced it with 5 amp slow-blow fuse and everything seems to be fine. My question is this:
The manual states "It is not necessary to consider high start currents... since starting and operating current are, for all practical purposes, identical."
How can this be true if the operating current (per the manual) is 0.8 amps and it was blowing a 3 amp fuse?
The motor is operated with a phase-shifting network ("C Connection", page 11 in manual below).
