Some higher end VFDs have line filters built in. Might want to check
to see if yours does before you
buy a filter.

Well, if you have interference problems, especially when the
spindle is running, then you may benefit from them. I had a
few things close to my mill that sh

Andy - that's a good point about "plug-in" equipment.
The lathe with original motor does not have a fuse, nor does my larger
plug-in lathe, nor my mill. All with capacitor start "2-phase" motors;
either 120v or 240v. My 240v circuit is fused for 15A. I generally only run
1 machine at a time, so on

I don't know what your standards are in the US, but as the lathe is
"plug-in" equipment it may be that it doesn't matter.

No, it is not overkill to fuse both (or all 3 with 3 phase) "hot" lines, it is
code.

Hi all;
Back to my CNC lathe project; it has sat dormant for a few years now.
Opinions wanted:
The VFD suggests 10a external fuses, plus a line filter. I'm running this
on 240v, over here in North America.
Are 10A slow blow 250v glass fuses ok for this application? Is it overkill
to fuse both
