- Installing new VFD (1phase 120v input with 3 phase output), 3 phase motor to Lathe
- I want to install a disconnect or on/off switch between the house 120v plug outlet and the VFD input. So I'll plug the VFD into the 120v wall outlet, but I want a on/off or disconnect switch between plug and VFD so I can shut off power to lathe completely.
I'm looking at switches similar to this and to get over 20A, everything switch seems to be 3 pole. Katko KU325
I'm going to need to figure out which is neutral in the power cord, right?
How can I make the 3 pole switch work?
