In our jurisdiction, you have to have a mechanical disconnect switch before any fuses, or electrical connections (such as VFD). So if your input is 220V 1`PH it is a double pole switch after the leade and before the VFD. If your input is 3PH it has to be 3 pole.should I wire directly in to the fuse box that was there.
