Pump panel for a 25hp on 208/120 system

[ptonsparky]

Disregard this calulation ptonsparky i looked at that wrong. I can go up to the next size fuse of 150amps, I also believe if the motor didnt start i could use the exception 2 and increase to 225% of the flc... I think what you were saying is that the panel presented has a max circuit breaker ct rating of 100, so if i have to go up to a bigger fuse than ill also need to go up to a bigger panel?

You are mixing circuit breakers and fuses, but yes, if you end up needing bigger fuses, you would need to jump a PP size. I doubt that will be an issue, but I’m here.

I'm sizing everything for a 20hp motor 208v 3phase. This is the pump panel i found in our warehouse. i believe this should be sufficient. plan is to install a 125a 3 pole inverse time breaker in my panel. i will then feed the pump panel with #4 . i will put 100a 250volt type h or k fuses in my pump panel. i will install a new raceway to controls inside. I will use #2 so cord to run up to the motor from the panel....
