The above is the schematic of a control cabinet feed for a 25Hp hydraulic motor.
To upgrade this machine to 75HP motor, I need to do the following:
1. Get rid of the fusible 60A and change it to a 150A breaker.
2. Change 1L's to 1/0.
3. PDB can stay, as it is rated 175A already
4. Change 1CB to 125A.
5. Change 1M and overloads to size 96FLA.
Everything is Cutler-Hammer.
What frame CH breaker would you use, and does this sound plausible?
edit: Hoffman 24x24 enclosure, no outside handle option.
