My new edge sander was delivered today, Grizzly 6x80. In the version of the manual on the website they list it as 1.5 HP 16A/8A. But in the manual that came with it and on the nameplate on the motor it says
1.5 HP 20A/10A.Now I should probably run a dedicated 220V line to it regardless, but for the time being I thought I was going to be fine on my 20A 110V circuit. I just think it's very weird because if it's really drawing
20A then why are they calling it 1.5 HP? 20A should give 2 HP. I was under the impression that they couldn't lie about the amps, but HP ratings were more fudge-able. It's a 1725 RPM motor, and looking at the motors Grizzly has in their catalog the 1.5 HP 1725RPM model draws 17A, whereas the 3450RPM draws 15.6. So I suppose that can explain a bit of why the number is higher than I expect, but not all of it. Have they just found a new source of really inefficient motors?I wired it for 110 and it ran fine with no belt on it, but that doesn't really mean anything. I need to build a stand for it and get it up on that before I start bolting on all the tables and whatnot so it's going to be a while before I can test it under load.
