Greetings,
I am wiring up a Teco 7300 VFD to a lathe.
Motor is 3HP. I have a separate on/off switch wired in before the VFD and after the main panel.
What size breaker should I put in my main panel and what fuse size should go in the on/off switch? I think 20 amp should be fine for the breaker, but what about the fuses in the switch?
I kind of backed myself into a corner with the switch as it takes the larger K size cartridge fuses(3"l) I did see that Bussman sells fuse adapters so you can use the smaller cartridge fuses.
Thanks for any help!
