Should my pool pump be hard-wired or plugged into an oulet?
The max rating is 25a so replacing the 30 amp breaker with a 20 will probably work. Most jurisdictions don’t allow a plug for a disconnect it would be proper to have a standard 30 or 60 amp rated disconnect , if it Tripp’s the 20 amp on start up you can use a larger breaker but because the MFG states max 25 that’s the max. You can always use larger wire so that is fine.
