Ralph, full kerf, that’s all I use.

And that’s pretty common for motors not under load. The more it has to work the more power it draws, when not cutting all it has to do is overcome frictional losses.

240V @5A is just over 1.25HP for a 80% efficient motor, no motor is 100% efficient. So @3A it’s using ~3/4HP just to idle.

Cyclones and dust collectors are the exception, they’re always under full load when running so they’re always drawing nameplate FLA. So keep that in mind when sizing things and it probably be best if you run it at 240V also because of that so it’s not pulling its FLA on one 120V leg.
